I was going to build up a IR laser since I have some NV equipment. I plan to make it 5mW or less.. Would I need eye protection still since it's low power? I would assume so since it's a non visibile spectrum and your eyes won't react to that light being shined in your eyes (assuming someone looks directly into the laser). What about reflective as well.. is it dangerous? I tried reading the FAQs but they don't talk about this specifically.. only warnings about the green laser producing IR.
