Hi and thanks for taking the time to read- I have been a 'good boy' and did all I could to both read the FAQ's here and do a search for any and all threads relating to safety but the 2+ hours I have invested in researching have yielded few answers.
I appreciate the opportunity to post on your message board and apologize if this thread is one of those annoying '20 people ask this question a month' threads.
So I implore anyone with scientifically grounded data to help me be safe with a 200mW green laser, probably IR unfiltered laser. The agreement I have with 'Rayfoss' for the purchase of the laser should include their goggles but I am skeptical of how much protection they will afford.
Please help me understand what is and is not dangerous using a 200mw green laser.
I've read as long as the dot is on a carpet, wall, or other relatively diffuse surface no danger exists either through the green or IR light.
At what distance will a diffuse viewing of the 'dot' prove damaging, on average? Is this damage permanent? At what distance will it be OK to view a highly reflected beam from a 200mW green pointer?
*most importantly* are there goggles that protect against both IR and green? Are there any goggles that protect against *all* wavelengths including IR?
If anyone has any info or a link for me that points to a really GOOD DEAL on eye protection as per above PLEASE help me to locate!
I have always enjoyed experimenting in the realm of biology and physics - have found lots of great deals over the years (like for example I was lucky enough to pick up a $7000+ stereo microscope- Nikon Smz-2T- for $500) but this latest fascination with lasers has me a little nervous.
Thanks again for the pros here to take the time to read, and thanks in advance for taking the time to respond!
