This is a step by step teardown of a Logitech webcam which is helpful if you are trying to build a stereo camera or adjust the focus.
Focus adjustments require making a lens adjustment tool.

The IR filter can be removed.
Wear eye protection.
Take a sharp pocket knife or utility knife and slowly, carefully score around the edge of the IR filter where it bumps up against the inside of the round lens body. Keep doing this around and around and around. Remove shards of material every couple of passes.
Try slipping a very thin jewelers screwdriver under the filter at various points along the edge where you have scored. If it does not get in, repeat steps above.
At some point enough of the filter will have been removed by the scoring process that you can slip the screwdriver (or whatever thin prying instrument you can think of) under the filter, and lever against the lens body to pop it out.
You will not be able to put it back in. Or if you can, I don't know how because I did not need to for my purposes.
I cut out the IR filter with a box cutter. Cut 1mm from the end at a 45 degree angle while holding the lens in place. The filter comes off after a few tries. Be sure to cut off any rough edges, as the debris can fall ontop of the image sensor and cause dark cluster defects.
