calculating laser eye safety

gallamine

Hi all,

I'd like some help calculating laser eye safety for a 905 nm diode laser system I'm building. It's for a scanning laser rangefinder and I need to figure out if my current design (a TOF rangefinder) can be feasibly be made Class 1 eye safe. The eye safety calculations are a little tricky and I'd like some help.
Thanks!

What standard covers this? What agency does the final approval? Is the final approval based on testing, or on submitting your design?

My end goal is an open-source open-hardware design, so there is no regulations other than my own conscience about putting out something dangerous.

My goal would be to meet the ICE Class 1 standard: http://en.wikipedia.org/wiki/Laser_safety#Class_1
