I’ve also noticed the focus issue after removing the IR filter. It seems thick/close enough to the ccd that I’m guessing the lens was designed to compensate for it. I’m assuming anything with about the same optical qualities and dimensions (an IR bandpass filter or at least something that doesn’t block IR) should fix the problem. I’ve been looking for something, guess I’ll just post again if I find a good solution.
In the meantime, I’ve found that I can at least get it to focus in the more zoomed in setting by stopping just before it ‘clicks’ into place. I haven’t looked at the mechanical portion of the lens, but maybe it could be adjusted/hacked/whatever to compensate properly?
Oh, and a fun picture of something I found by accident while testing it without the filter - the end of a lit cigar just below ‘red hot’ looks kind of cool in IR. (image quality went to crap when I actually got a shot of it, oh well)

pdehn, this is exactly what I did. Until we find a way to disolve/remove the glue that holds the lens, the temporary solution is to rotate the lens between the ‘clicks’ and get the sharpest image that way. Another solution would be to get another lens holder and use 12mm lens without IR filter found on eBay.
As you can see the camera sensor is very sensitive to the IR (with filter removed), which is great news for us at NUI Group.
I got my PS3 EYE today, took out the IR filter, and noted the same focus issues that you guys were having. I was able to fix it by simply sanding down the edge of the lens mount that contacts the PCB, thus bring the lenses closer to the sensor. There is still plenty of room inside of mount for the sensor. You will of course lose the little pins that help you align the mount to the PCB, but once it is screwed down, it should not matter. Obviously, you cannot undo your changes with this method, so you should probably work slowly, checking the focus as you go.
I removed the IR filter of my Eye webcam just now. Really easy, not as damageful as I thought. I made a little tutorial.
Also, if you keep intact the IR filter, wouldn’t it be possible to use this technique to remove the IR coating? You would then be able to place the filter again but it would let the IR pass through and you would keep the focus intact as well.

Hope that helps. I will try the instructables tutorial if I find the abrasive cream.
On most webcams there is an IR filter because the CMOS sensor of webcams is sensible to IR light. Without the IR filter you can clearly see that the colours are not natural at all, they seem more black&white (kind of like CCTV images). So, the IR filter is here to let only the visible light spectrum to be present in the final image and make them more natural and “normal” for the human eye.
how the hell do you remove the back panel? Do you pull it straight back twist it push it down. I have no idea how to take this apart. Can someone post a more detailed tutorial on removing the back cover. I have been at it for like 2 hours and don’t even know where to start!!!!!!!!!!!!!!!!!
I understand to use a screw drive I need to know where to put it. The are 3 components the from the back and the kidney shape on the bottom. Do you pry it apart near the cord, near the bottom of the lens, or under the card at the seam of the kidney shape and the back plate?. Sorry if this is vague description but I can’t think of a better way to describe it.
haha, i understand what you mean...pry it at the part next to the lenses...there isnt much to damage there if you poke it in too far..You’ll notice it is the most held together area, due to the stand, so try there the most.
