advice for high power burning class 4 laser

[upaa27]

Assuming equal reflectance for all visible wavelengths, it comes down to a) beam power, and b) the eye's response to the wavelength in question.

If green, your pupil will constrict, blocking out most of the light.

If violet, your pupil will probably not constrict, because it's not a very visible wavelength. That will allow much more of the light to enter the eyes.

That would make dimmer wavelengths more "dangerous."

Ok I understand. Guess what I meant was that colors like hot pink and green are "brighter" than the rest as they are at the top of the visible spectrum. Then again I have only really made some 445s and one 635. Thanks guys.
