Hi Gary: Laser safety-glasses are essentially colored filters, the color chosen so as to absorb the particular laser wavelength you are working with. The best ones, like sunglasses, have the filter material homogenously distributed in the plastic lens itself, so a scratch doesn't open a potentially dangerous "leak". You have to choose the safety glasses to match the laser you're using. Edmund used to sell several wavelengths, but I haven't checked in years. I just performed an experiment. Held a #58 green filter in front of my class IIIa laser level. The spot was attenuated severely, easily lost at least 80% of it's intensity. Laser light is still just light, and will respond to filtration the same as incoherent light. Chuck --- Gary Liptrot <n7zi@comcast.net> wrote:
Does anyone know what the characteristics (specs) are for a pair of "Laser Resistant Glasses"? What makes them resistant to the laser effects.
