I've ordered these googles:
Portable Protection Goggles Laser Safety Glasses Green Blue With Velvet Box HC | eBay
..but I don't understand what this line means:
Attenuation: (10-6 < N% < 10-4).
I was hoping someone could help by explaining this.
OD5 and OD6 I think are powers of ten, so factor of 100,000-1,000,000 less light passes through the goggles over the wavelengths it's designed to attenuate?
I assume said goggles are useless at blocking any IR the laser emits, but at the powers of laser I own and lack of IR collimation I should be OK.
