Hi, I am looking for some kind of lense to mount infront of a small photodiode sensor (TAOS surface mount chip) on a PCB. I want this lense to allow the sensor to view colors better at a distance of 10cm (As apposed to close up, under 2cm), so something like a fixed 'zoom' lense i guess. So my question is, where would i get such a lense ?, what would it be called ? (i have seen the word 'collminating' all over google when searching for lenses, is that what i want?), and how would i mount it. Are there standard lense mount mechanisms available ? something that would sit straight onto a PCB ? what are they called, where can i get them . I can blindly stab around at what i want, but if anyone has experience with this kind of stuff, please point me in the right direction . much appreciated, Alex.
