Just as a note for anyone doing this, make sure you don't get any dust or whatever on the sensor while you're getting the filter out. I've got some small dust spots in my video from the back of the lens. Not an issue for my use case but something to keep in mind Thanks for the video, very informative. I'm using my camera for IR head tracking and needed the filter taken out :)
I modified my old Logitech quickcam pro 9000 following your tutorial, everything was same except for the IR filter. Mine was in circular shape, I had to break it to remove it. Anyway it worked. Thanks a lot!
Thanks, Just successfully did this with your tutorial. I did turn the lens a little more for infinity focus. The focus still works fine, I was kinda worried about that🙂
Heads up, I recognize those bits and they are made with a rather low quality of steel. There are many times I've stripped or chipped the bit and not the screw. I definitely suggest getting yourself a premium bit set and use whichever driver you like.
I have a question to your rebuild. After remove of the IR filter is everything blurred on my camera. Is this behavior normal? I thought every picture is like red because of the missing IR filter but I didn't expect that the result is blurry. Is that behavior normal or did I make a mistake by the modificaction
IR has a different wavelength, and requires a different focus point on the lens. So the behavior you observe can be normal. This is why on professional cameralenses you can see a white focus marking on the lens barrel, and a red side marking next to it with f11 and f22 written around it, which is the infrared zone focusing range.
Not sure about the connectors at the end, but if it's just 4 wires with USB on the end, they should be interchangeable. If the wires are red, black, green, and white on both, you're good.
No. Most IR filters do not. UV filtering happens by most pieces of glass already, depending on what UV type you are talking about. UV-A tends not to pass glass well already, while UV-B can pass it a bit. UV-C is definitely bad and is typically much better at passing surfaces. After all: it's the kind that tans your skin. But a UV-C producing light requires quartz-glass, otherwise it'll be blocked inside of the producing tube already.

can that dust be cleaned if it gets on the sensor itself ?
without removing the filter, the camera sees infrared diodes

Great, thanks! Can you share some IR camera pictures with a daylight filter on top?

I followed along and everything went great thanks for the video

did u have the vid for you remove the filter
Pro tip put tape on the glass first so you can pull out easily. Makes it easy to remove.
So, did the webcam still work after you flexed the solder?
Thanks for doing this.

is it possible to replace the cable on my c920 with the cable from a broken c270 HD are the cables exactly the same?

Yes usb 2.0 is all the same
Does that IR filter blocks UV light too?
No. Most IR filters do not. UV filtering happens by most pieces of glass already, depending on what UV type you are talking about. UV-A tends not to pass glass well already, while UV-B can pass it a bit.
UV-C is definitely bad and is typically much better at passing surfaces. After all: it's the kind that tans your skin. But a UV-C producing light requires quartz-glass, otherwise it'll be blocked inside of the producing tube already.
Great
