Wondering if you could offer some advice. I'm looking for a very safe, very low power IR laser diode.
requirements
>800nm
I think a Class 1 or Class 2 rating would suffice.
It must be safe to use around animals and humans.
Cheap.
Is it possible to use an IR diode from a DVD burner in combination with, say, a potentiometer, to achieve very low power ratings, perhaps ~1mW? Or will the relatively high powered laser diodes simply not work at these low levels?
The application is a' laser tripwire' that fires a camera. I'm currently using red laser pointer diodes. I want to replace these with IR, since I want to photograph wild animals (and so desire an invisible 'tripwire' that is safe).
Thanks in advance for any pointers (no pun intended).
