I posted this question because i thougt 808nm is close to co2 "10,6", as I read it as 1060 and in the graph 806 an 1060 have the same 90%. But now i get is that it is 808nm and 10,6um. ronald

Can i use a Polycarbonate 2,5mm window as safty for my 40w coherent brick laser. It's rated at 808nm. I did some research but i,m not sure if it is enough. In the book "laser safety guide" they say it is used to block 10,6uM, but wil it block 808nm?? I also will we wearing 4od safety glasses...
