Hello,
I've two laser diode possibly broken.
All laser is tested in a close box using a webcam (a.k.a. eye security ).
One is a IR from a CD-RW, it absorbs current from 10mW to 15omW, but emit low light, as comparison i've other IR from CD-RW, up to 30mW laser beam begin to blind the webcam sensor, so i suppose this one is broken, could it be?
The other one i do not know which type of diode is, i've tried different pinout. It only suck current but do not emit any light.
For this last one the question is the same, it is possible that a diode absorbs current but do not emit light? I mean, i thought that a broken diode does not absorb current.
thanks!
