It looks like you took a picture of the front side of the lens assembly, so may be the IR filter is in the other side... as you mention, the ir filter is normally located nearest to the webcam sensor but sometimes they are a film "Glued" to one of lens... let´s see more pictures !!! BTW is this your webcam??? http://www.free-track.net/english/hardware/filter_removal/a4tech_pk_333MB.php Edited by fzfq3m on 24/06/2009 at 00h58.

Everything else was clear well, based on what you say then that´s the ir filter... unfortunately removing such kind of IR filter is beyond my skills... as far i know it can be removed using a rotary tool with felt polishing attachment and some polishing compound.. i never tried myself... look at this case: http://www.free-track.net/english/hardware/filter_removal/labtec_webcam_pro.php maybe somebody else has experience removing this kind of coating regards
