So I'm trying to build a prototype product in my spare time, part of which uses a laser torch (a bit like a laser genetics ND5). It needs to be as bright as possible but still safe (class 2m).
Does anyone know the maximum power density (mw/cm2) allowed for a laser to still be in class 2m?
Also, I guess this has to be the power density at the narrowest point of the beam (i.e. directly when it exits the torch lens) - right? I which case, I figure to make it brighter without going over the power density limit for 2m, I can just increase the size of the exit lens. Right?
Is there anything else I can do to increase brightness while keeping the thing in class 2m?
Thanks, and sorry for my naivety!
