I finally got my fresenel lens, and it works just as I expected = great! The image is a bit blurred, but then again, the tradeoff in image size is definitly worth it! The lens magnifyes my 19" monitor up to around 27"! Add shutterglasses to that, and you got the best immersion possible whatsoever! I´m serious! |

My eyes are around 50 - 60 cm from the screen. I can actually sit closer to the screen without eyestrain now. The fresnel lens gives the illusion of the screen being about 10 cm farther away. The FOV should be somewhere between 70 and 80 degrees I think. |

So that is 70cm from a 27" screen. It's wonderful. Regarding to 3D glasses, I found that you can get very very close to the screen without eysstrain. I mean very close, to a point my nose almost touch the screen. |

If you box in the fresnel lens so there is no ambient let getting between your monitor and lens it will help with the edge blurring. I used black foamboard from one of the craft stores. I also used spray tack adhesive to glue black T-shirt material to the inside of the box to eliminate any glare. You'll find the clearity and contrast will seem to double. John |

Lars, Two questions for your monitor: Does the tube surface have some sort of anti-reflection coating? I gues that'd help against blurryness by eliminating light bouncing back and forth between the screen surface and the fresnel lens. Is it a flat tube (like e.g. Sony Trinitron)? That might also help sharpness, as the distance between the screen and lens is constant. A curved screen would result in a slightly shorter distance from the screen center to the lens that from the edges. ...btw, where did you buy it? Alex |

" By Anonymous on Tuesday, July 06, 2004 - 03:04 pm: i got serious eyestrain with fresnel lens i bought from www.icetec-uk.com. and many reflections from my monitor too. something i doing wrong? " - Eye-strain is not something that goes with the fresnel lenses I supply at icetec-uk. I would suggest the postee is the same one who posts other anonymous messages elsewhere to discredit icetec. We have been selling fresnels to customers in the following countries: USA, Australia, Denmark, Sweden, Germany, Holland, UK, Canada and other countries. The only complaint we've had so far is from one customer who demanded a refund because he was expecting "3d-glasses". Even though our ad used the word fresnel no less than 40 times this particular customer still thought we were selling 3d glasses. He was issued a refund after which his response was to contact e-Dimensional and report us for mentioning that the fresnel worked well with their glasses. We actually have an email from e-Dimensional saying it's fine to mention their product and to refer customers. And by the way... This anon postee who claims our lens gave him eye-strain. He has just been identified as one of our customers who reported having received a broken fresnel. He asked if we would send him a replacement. He was told that this was possible providing he send us the damaged lens or send some pictures via email. He never contacted us again after that. If anyone is in doubt about the quality of our fresnel then either purchase one (we offer refund if not satisfied) or arrange for a demonstration. Our lenses are of such high-optical purity and with sufficiently high facet density that eye-strain is not an issue. The lens is so good that it can be used for hours without eye-strain. Provided of course that it's no greater than 7 inches from the screen. Just to recap: Anyone who wants to try one of our lenses can ask for a refund if it fails to live up to it's promise. I would also suggest you look us up on eBay and checkout our feedback (icetec-uk). You can also see some of the lenses we've sold to customers and their comments. The eBay feedback system is a pretty good indicator of integrity. |

PS. Interestingly enough we don't have a single customer who reported blurry image or eye-strain to us. You might ask how the anon postee purchased the lens from us? Was it via eBay or direct from the shop? |

" By Anonymous on Tuesday, July 06, 2004 - 03:04 pm: i got serious eyestrain with fresnel lens i bought from www.icetec-uk.com. and many reflections from my monitor too. something i doing wrong? " - Yes. Bullshitting. If you had a genuine issue then you would have contacted us or posted on our forum. We have a voting poll so that customers can rate the lens from good to bad. You have been identified as the customer who tried to scam us for a free lens. We have your email and your residential address. Did you imagine that you could go undetected? You were given a fair offer to receive a replacement lens for the one you claim arrived broken. All you had to do was either return the broken lens or provide pictures of it. Instead you chose to post false messages about us on this forum. You have spent the past few days arguing with elsewhere in this forum. You have called me a liar and insisted I only came to this forum to sell lenses. Although I can tolerate someone with a difference of opinion regarding VR technology. I won't tolerate someone lying in order to damage our reputation! You're obviously not quite old enough or smart enough to understand the possible consequences. Considering you come from the land of eternal lawsuits then don't be too surprised at the outcome! And for anyone who is wondering about anon's "reflections from the monitor" - A fresnel lens unhoused will reflect light. We sell neoprene to line the inside of the lens housing in order to cut reflections to an absolute minimum. Furthermore we use extention side-panels to further minimise light reflections. The result is a breathtakinly bright and clear image and an incredible immersive experience. "anon" didn't order the neoprene from us. Just the lens. And he then tried to scam us by getting a free lens as a replacement. If he'd sent us pictures of the broken lens or returned it then it wouldn't have been a problem! |

Lars Ahnland: "I finally got my fresenel lens, and it works just as I expected = great! The image is a bit blurred, but then again" Try moving the lens closer to the screen. As close as 4.5 inches would be recommended. At this distance the clarity and sharpness is at it's best and the bonus is that the FOV and sense of immersion is greater! This is because your eyes are closer to the lens screen and the screen thus expands to fill your peripheral vision! |

"Feathers632/ Feathers please keep your comments short and to the point. Avoid sales pitches please. No fighting. All these are against the rules for these boards." - I will make this short and to the point. I have no problem to abide by a rule of no-sales-pitching. No fighting? Happy to oblige there as well. But if you have a policy of allowing forum members to slander business without any thought to whether or not the postee is telling the truth or not - then you're letting yourself open to a whole can of trouble. Who could respect a forum where it's one rule for one and no rules for another? I like talking VR and that includes fresnel. I can certainly avoid mentioning my particular product. Likewise I would expect the forum to show some care and concern where it's members attack other companies or businesses. In this instance we have a good case against the postee in a court of law (especially since the postee is known to us). I have made comments elsewhere about the i-glasses HMD. Again it would be reasonable for IO to respond in such an instance. The difference here is that my statements are based on experience of their product and known problems. But again - if the forum asked me not to mention the company then I would be happy to oblige. If you're going to apply rules then apply them fairly! |

"I finally got my fresenel lens, and it works just as I expected = great! The image is a bit blurred, but then again, the tradeoff in image size is definitly worth it! - Lars... I'm pleased to see that your overall experience of the fresnel is a good one. If your image is blurry then this might be due to the facet density or simply due to the distance from lens to monitor. When using a fresnel it's important that it's positioned such that your eyes view through the center of the lens. If you can raise the height of the monitor to match your head-height then this will give much better performance (in terms of immersion). I don't know if that lens+hood you purchased would allow you to move the lens closer? If so then it might improve the clarity. The lens and hood systems I sell have the lens set to 4.5 inches. This gives exceptional clarity and also increases the field of view and thus the sense of immersion. If you can modify your fresnel and move the lens closer then you might gain that image sharpness. In essence what I'm saying is that a fresnel doesn't=blurry image so long as it's well designed. This is not sales pitch but intended as helpful advice. Lars originally approached me many months ago when he was considering purchasing a fresnel. Although he decided to purchase elsewhere. As a VR enthusiast I am happy to offer advice or suggestions. |

In all honesty, i must say that I dont get this infinite focus point with my lens. The makers, Lessgauss, claim it´s a fresnel lens, but I´m starting to wonder. I´m still happy with the magnifying effect however. That was what I was after, and I got it. |

It's a different fresnel to the type I sell. Yours has vertical and horizontal lines, yes? I don't know how it compares to ours. To anonymous: We are taking legal action against you. You will be notified over the next few days. You can expect an email and then a letter. Once the case is done then we will probably follow it up with a web-page detailing the activities of this conman. For anyone who is mystified by this argument? This anonymous person who frequently adds "ho ho ho" to his messages spent several days arguing with me in another thread. We later discovered that this person had posted another message (in this thread) claiming to have received a lens from us and suggesting it had caused eye-strain. The stupid thing is that all customers we've sold to have given us good comments. But there was one customer who claimed to have received a damage lens and then tried to get us to send a replacement free of charge. We said it was fine so long as the customer either returned the damage lens or sent pictures via email. The customer said he'd send pictures and that was the last we heard from him. But it now transpires that he has been posting anyonymous messages in order to damage our business. In other words: Because he wasn't able to scam us for a free lens then he responds like some spolit pre-teen by suggesting our product is defective. To anyone who might therefore be in some doubt as a result of his campaign - I would suggest you check us out on eBay. Username: icetec-uk or through our website. As you can now see - this conman is now trying to convince us that he's forum moderator here. I would suggest that any genuine forum moderator is educated enough not to post anonymously. Conman: We are taking legal action against you. |

Not the brightest button! To date: After purchasing a lens from it was shipped to his address. The customer then claimed it had been damaged in transit. Not a problem. Simply provide proof by either returning the lens or sending pictures of it. The customer then went silent on us. It now emerges that this customer (upon realising that his scam to obtain a 2nd lens had failed) posted an anonymous message claiming to have received a lens but found it to be of poor quality. So determined was this customer to damage our reputation that he kindly put a link to our website. If you look at the structure of his post - it has the feel of someone setting out to damage the reputation of a business: " By Anonymous on Tuesday, July 06, 2004 - 03:04 pm: i got serious eyestrain with fresnel lens i bought from www.icetec-uk.com. and many reflections from my monitor too. something i doing wrong? " Notice how brief the message is? It's as if this person doesn't really have anything to say about the lens but is simply trying to cause damage. "i got serious eyestrain with fresnel lens i bought from www.icetec-uk.com." - Someone with a genuine case would go into more detail. This person is effectively saying: 'i bought a defective product from icetec-uk. He tries to make it look a little more genuine by adding: "and many reflections from my monitor too. something i doing wrong? " - The purpose of the message is therefore to associate icetec-uk with defective products in as few words as possible. "something i doing wrong?" is simply for effect. He has already implied that the fault is with icetec-uk. It doesn't take a genius to figure out that someone who would try to get a free lens by lying to a business would also be dumb enough to follow up with slander if he couldn't get his way. This conman spent several days arguing with me in another thread on this forum. He tried every trick in the book to stop me posting (even asked why the moderator hadn't banned me!). In a final act of stupidity he suggested that no vr experts would be interested in visiting this website or forum. I happen to know that quite a few experts visit stereo3d.com! So as well as trying to get me kicked from this forum.. He then suggests that this forum has little value or interest to professionals! (duh?). Did I say it was his final act of stupidity? Not quite! In this thread you can now observe that he is posting is such a way as to convince forum members that he is a moderator here. No moderator with any intelligence or common-sense would post anonymously! And finally - regarding the days of arguing in the other thread... He stated repeatedly that I had no place discussing fresnel lenses in that other thread "this is a thread for stereo 3d users..." Do you know what the title of that thread was? "If you like fresnel, check this..." And the link is here: http://www.stereo3d.com/discus/messages/24/2766.html?1090841168 If you're dumb enough to scam a business for a 2nd lens - followed by a campaign of lies and slander... Then you're not going to be smart enough to avoid legal action. Right? |

I just want to say that feathers' comments have been incredibly detrimental to the board. It is fine for somebody to say that they dislike a product on a public message board and would in no way be considered slanderous to a business. Also, on previous threads, feathers presumes to be much wiser than others on this board, which is pretty damn arrogant. In regards to posts on the thread linked in the last post, Anytime you have a simulator, you want to set the focal plane of the image to the approximate distance of what you would be simulating. If you are simulating a cockpit of a tank or plane, you would want to set the focus of the system to be focused at much closer than infinity, as you want the simulation to be as accurate as possible. Also it is a bad idea to focus an image plane at infinity EVER in a virtual reality system, because most people arent 20/20 even with their glasses. It is much better to focus slightly closer than infinity. |

Are you a fresnel lens user? Your wording suggests a total lack of experience with fresnel lens technology. Put quite simply: A fresnel extends the focal plane. Whether it's set to infinity or not makes no difference. It doesn't make objects look small. It's effects are difficult to describe. You're not really aware of the effects on a conscious level. But the extended focal plane serves to make the images seem more realistic. Thus (contrary to steve's words): you don't need to choose a fresnel with the focal plane set to a point closer than infinity. It's a totally pointless argument and anyone who has used a fresnel system for any length of time would understand. "It is fine for somebody to say that they dislike a product on a public message board and would in no way be considered slanderous to a business. " - It is fine, is it? Is it fine even when the comments are untrue? If any other lens customers had reported eye-strain or blurry image then I could accept. But this has not been the case. The attack was simply made by a disgruntled customer who sought to obtain a free lens by deception. As director of icetec-uk - I am not entitled to fight such an attack? I don't give a damn if you don't like the effects on this board. You obviously don't give a damn whether the attacker's comments about eye-strain are true or false and that tells me a whole lot about your sense of fair-play and rationality! I would suggest that forum members who support a conman and condemn the victim make this forum a much nastier place. Certainly very detrimental! |

"to say that they dislike a product on a public message board and would in no way be considered slanderous to a business." - Your lack of understanding and rational thought beggers belief! So basically it's fine for anyone to enter this forum and say whatever they like about a product. You're not concerned one bit whether it's true or false? But - you don't like someone defending themself or defending their product. That is seen as detrimental to the forum. I notice you have nothing to say about the person in question. That speaks volumes about you shows a lack of integrity. |

"Also, on previous threads, feathers presumes to be much wiser than others on this board, which is pretty damn arrogant. " - Wiser? You mean wiser than someone who spends several days telling me I shouldn't be discussing fresnel related issues on a thread created for fresnel discussion? Or wiser because I come to this forum and dare to know a thing or two about the fresnel lens? Your comments ("steve") would suggest that you know absolutely nothing about the fresnel and it's effect. Is that an arrogant statement? Damned right! But it's also a true statement. Your comments about the fresnel and the issue of infinite focal plane are absolutely and totally irrelevant to the use of the fresnel lens. It's not coincidence that most such comments come from people who've never used a fresnel. So you don't like it because I come here knowing more than you about the fresnel? Tough. Am I wiser? I'm wise enough to know that it's not acceptable to post negative comments about another website or it's product and then to sit and complain when that particular business then tries to defend itself! If you have rules - apply them fairly. No advertising or selling of products on this website? Fine. I am still happy to post as an enthusiast. But then I would also expect that posting slanderous comments about another website or it's product should also be treated seriously! There is after all the issue of whether or not such comments are genuine or simply due to a disgruntled customer seeking revenge! I would hope that there are at least a few adults posting on this forum as well? Perhaps with enough experience of the fresnel to understand that: "i got serious eyestrain with fresnel lens i bought from www.icetec-uk.com. and many reflections from my monitor too. something i doing wrong? " Reflections are inherent in any type of lens. Fresnel lenses are no exception. If the customer had genuinely used one of our fresnel lenses then he would understand that reflections can be minimised to a very low level by the use of neoprene. So to complain about reflections is as irrelevant and as ignorant as suggesting that a fresnel lens wouldn't work if it's focal plane is set to infinity (thanks for that one - steve). Do I come here knowing everything? Absolutely not. I come here knowing about fresnels because I have the damned experience behind me. If some of you don't like that then go and learn something about the fresnel yourself! And have the decency to make your slanderous comments without hiding your email address. |

"Also it is a bad idea to focus an image plane at infinity EVER in a virtual reality system, because most people arent 20/20 even with their glasses. It is much better to focus slightly closer than infinity. " - Hmmm... That must mean that fresnels create problems since their focal plane is fixed? If you can't vary the focal plane then a fresnel won't work the same with all games/simulations (that is what steve implies). What is the reality of using a fresnel? Even though the fresnel has a fixed focal plane. It gives the same results with any 3d game/simulation. It has the effect of pulling you into the game (immersing you). It does not make objects smaller or only work with certain games. If you have a 3d game or simulator - then the fresnel will give you an incredible experience. People who actually try the fresnel usually say the same thing - it works great. They don't report focal plane problems because focal plane problems aren't relevant (whatever game or simulation). Put simply - the people who make such statements about the fresnel are usually the ones who have nothing but second hand information or hlaf-baked wishy-washy theories. I use the fresnel for games-playing. I use it with and without LCS. I sell fresnel systems to people around the world. They don't complain about reflections or infinite focal planes because they know such things aren't an issue. While some of you are endlessly discussing the theoretical problems associated with the fresnel: others are using the system and getting great results. While I am considered arrogant (by the likes of steve) for daring to know something about the fresnel - I would suggest it is much more arrogant (not to mention - dumb) to list theoretical problems about a system that is tried, tested and proven to work! And let us not forget where this damned system originated? It was first proposed by the U.S. naval research center and has been the basis of many military and civilian simulation systems! And of course the technology eventually found it's way into gaming arcades! Now I suggest that it's pretty arrogant to suggest that such a proven system has problems to work because of fixed focal plane or infinite focal plane! If you don't like my tone of voice (or typing) then tough. If you criticise me for defending myself then I can criticise you for spouting garbage! |

"Also, on previous threads, feathers presumes to be much wiser than others on this board," Based on steve's comments about fresnel focal plane problems with simulators then I would also agree that feathers knows more. I think we have a simple case of someone resenting someone else for having a better knowledge of something! Should feathers come to this forum and pretend not to know about fresnel lenses to avoid to offending someone else's ego? Also the comment steve made about slander not damaging a company or product is totally absurd. |

Lol! This is funny to watch. Here's my take on things Whilst feathers has plenty to say (http://www.stereo3d.com/discus/messages/24/2766.html?1090841168 ) i can't say i have a problem with him. Some of his posts in the fresnel thread are hilarious (especially the courtroom drama!). From what I've read on this anon guy (in this thread and the fresnel one) it does seem like he has a mission to stop feathers from posting. If you check-out the fresnel thread you can clearly see that the anon guy (feathers refers to as "the attacker") repeatedly tells feathers that he shouldn't be discussing the fresnel as "it's a thread for stereo 3d". Feathers quite rightly points out (somewhat humorously) that the subject of the thread is "if you like fresnels..." It looks to me like this anon guy is seriously trying to stir things up! I also noticed something else that feathers mentioned in this thread. He points out that even though the attacker posts anonymously he still uses the same words and phrases in this thread that he used in the fresnel thread ("ho ho ho" being one particular example). I gotta say that the post near the top of this thread :: " By Anonymous on Tuesday, July 06, 2004 - 03:04 pm: i got serious eyestrain with fresnel lens i bought from www.icetec-uk.com. and many reflections from my monitor too. something i doing wrong? " :: does look more like a lame attempt to damage someone's reputation rather than being a genuine gripe. As feathers points out, it's as if the guy just wants to associate that website with a bad product. He doesn't go into any detail at all. I also checked out feathers eBay feedback and it's pretty good. His business has sold more than 100 items and not a single bad or neutral comment! If I was a betting guy I'd put my money on feathers. The anon guy looks too much like someone with a personal grudge as far as I'm concerned. I'm siding with feathers on this one. Being attacked for defending your business is pretty lame in my books! I also gotta agree it's unfair to have a non selling/advertising policy and then not to give a damn when someone posts slander about a product! |

I'm with feathers too. It's always nice with people with knowledge. It's just up to us to filter the crap away and I think most of us with a little brain could do just that. Little long posts though feathers. Your info have given me the push I needed to try one out. Note, that I was thinking of one before I read these posts :-) |

:-) Fresnel is the only way to go until the VR Helmet is sufficiently developed to cope with the latest games. Doom 3 looks pretty scary through fresnel+lcs 3d glasses! I've just reached the level where the spiders appear. They're pretty scary (as are the other monsters). Just to explain what the extended focal plane really means in practical terms: Extending the focal plane means your eyes can be much closer to the surface of your computer screen and yet still be able to focus. Because the focal plane is extended far behind the monitor and coupled with the lens magnification then this gives you the effect of a very large screen (cinematic). To explain it another way: Bring your eyes approx. 6 inches from your monitor... As you do this then the monitor image expands out to fill your vision. Unfortunately your eyes are no longer able to focus properly. The fresnel changes all that. Your eyes can now be close to the screen and yet the image is magnified substantially by the lens (and also because your eyes can be closer to the monitor screen). With the fresnel your eyes might be 6 inches from the screen (for example) but focus is no longer a problem. The focal plane has now been extended far behind the monitor. The image remains sharp and clear but has expanded out to fill your peripheral view. I hope this explains more how the extended depth-of-focus works? Damn... Yet another long post. I will work on making them shorter. |

Hi I have some Q. I think you have said on this board that the game "Lock on M.C." doesn't look so good with the lens but on your web site it says that it works very well. If I'm wrong, sorry, if not, explain please. Since the lens is about 12" if I have understood things right, it really doesn't do me any good if I have a 17",19" or even bigger. It would be enough to have a 14" is that right?? Thanks! |

Hi This was from your site"One of the worst programs for Fresnel+LCS is "Lock-On Modern Air Combat"." This was from the board" LCS+Fresnel works best with FPS and Racing games. It's also pretty spectacular with flight sims such as FS and Lock-on." Just wanted to get the right info :-) |

Jesper, Some games will always look better than others with the combination of fresnel+lcs 3d. Just to make things clear: All 3d games/simulations are enhanced by the fresnel. You get the feeling of being dropped-into the game world. LCS 3d glasses also make any 3d game look better. The point is that when you use the two together then not all games look as good. Lock-on has quite washed-out/faded textures and this doesn't work so well when you add LCS glasses+fresnel. Since we now set our lens to approx 5 inches from the monitor (by default) then it's no longer a problem. It was a serious problem with the very first version of our fresnel though (different focal properties). The problem is that LCS 3d glasses (although wonderful) incur quite substantial light-loss as well as some degree of ghosting. All 3d games/simulations look great with the fresnel. All 3d games/simulations look great with 3d LCS. Not all games look as good when the two systems are used together because of the light-loss incurred by the LCS. If you're thinking right now that perhaps you'd be better off without fresnel or LCS for some 3d games then you'd be wrong. The fresnel beats conventional gaming every time because it gives you large-screen cinematic gaming that drops you right into the action. I'm simply stating that some games look better than others with LCS 3d and fresnel combined. So long as our fresnel is set no greater than 7" from the monitor screen then it works fine with our without LCS 3d for any flight simulator or 3d game. |

"One of the worst programs for Fresnel+LCS is "Lock-On Modern Air Combat"." - Some of the info on the site is due for an update. If you see some contradictory statements such as the one you highlight - it is simply due to changes/improvements made to the system. Our very first fresnel was set to 12" from the monitor. This gave very poor results with Lock-on when LCS 3d was used. We now set the lens to a max.distance of 7" inches. If you want maximum performance then it should be set to between 4.5 and 5 inches from the monitor. We have also made substantial changes to the lens hood compared to the original prototype and this further helps to produce a bright, clear image. So, to answer your question: The fresnel+lcs 3d combination now works fine with Lock-on. |

No the fresnel and glasses work FANTASTIC with LO-mac. I just wish I didn't get my ass kicked so much while flying the game. WWII planes I rock, Jet's I suck John |

You should be very happy about the new WWII fighter sims on the way then? I saw one of them mentioned over at http://www.gamershell.com/ a few days ago. |
