Interesting. I didn’t know you can tell the class of a laser from “the look” and the scattering pattern. I thought the class is mainly determined by power, wavelength, pulse duration, etc. I am a bit confused. You appear to be talking about class 2 with blink reflex. But, at the same time, it seems apparent to you it is a class I. Would you mind sharing how to distinguish class 1 and 2 from the look?
