IBM PC Camera Disassembly

I just took mine down to this level wanted to post an update. On my cam the glass embedded filter on the cmos chip is NOT the IR filter. If you look at it and tilt it at an angle it lacks the red reflection that indicates IF filter properties. However, if you look into the focus/lense assembly at the objective lense you will notice this red hue!! To get at the true IF filter, you have to CAREFULLY loosen and remove a small black disk on/in the REAR of the lense assembly. On mine there were two drops of glue holding it in. Take care NOT to loose or break the small lense at the very rear near the plastic retaining ring as focusing the camera will be impossible without it. The IR filter is a small square piece up in the front of the focus knob. If you have removed the true ovjective lense from the rear you can use a mini screwdriver or even a pair of tweezers like I did to pop it out. Add a dab of glue to hold the remaining lense to retainer ring in the REAR of the focus assembly! I you simply push the objective lens up toward the front where the IR was you won't be able to focus as the IR filter also acted as a spacer to set the objective lens to the correct focal length.
Peace and God Bless!

Thanks for the tip, Austin! I'm glad I don't have to try to take the imager chip apart . . . and then find out it has nothing to do with it.
