Hi guys, help me if im wrong,
Class I and II laser no need glasses = under 5mw.
Class III laser yes = over 5mw.
Now i know how to choose the wavelength, but i don't know how to choose the OD safety level, because i don't know how to compare the laser output and power to the right glasses... So i'm actually using this logic...
IF:
OD1 = 10^1 = it means that light is x10 times less bright.
OD2 = 10^2 = it means that light is x100 times less bright.
OD3 = 10^3 = it means that light is x1.000 times less bright.
So the goal is to keep the light power same as the light that can produce a simple laser pointer """"under 5mw!!!""". Because we can immagine that lasers under 5mw """no need glass protections""".
for exemple: 1.000 mw laser/1000 = 1mw. = It means that if i wear an OD3 glasses i can see the output as a simple 1mw laser pointer, and that should be enought, and it's not possible that if the bright is x1.000 times less it can still make you blind... I think that """with the right wavelength glasses""" the brightness is directly proportional to the output power.
right???
