With amazing persuasion skills I've convinced my management to let me buy some flashlight parts to make a replacement for an outdated incan and filter arrangement.
Problem is, I need a specific wavelength (green, ~525nm) and a bandpass filter. The bandpass I can get from Edmunds for only about 25$, and the diodes I can pick up pretty much anywhere on MCPCB or reflow them myself.
The issue is... the housing, case, and pill. And finding a regulator that will do 5ma and up enough that I can experiment with to make sure I fall within spec and do not fog the medium being exposed.
PWM is out- I need true CC (or at least a PWM so very high that at such a low intensity it isn't able to fog the chemical films).
Are there any US suppliers of parts for flashlights that ship fast? Cost isn't an impossible objective.
Suggestions most welcome.
