So there's these goggles... Od ^9 from 190-375nm's.. Not technically in a 405 bluray lasers wavelength but do they work? They sure appear to block the light... Thanks.
Well I don't know what you mean by "off" exactly... I doubt the ratings are inaccurate. I'm guessing it just provides a Lower level of protection for the 405 area. Or maybe its close enough to the 190-375 that it gets filtered anyways...Where do you see the 405nm wavelength in the ratings? I said the specs are off. I did not say its crap.
thanks yea that's what I was thinking but didn't know how to word it properly. lolJut because the goggles don't say they block 405nm doesn't mean the specs are off. The specs would only be off if they said explicitly it doesn't block 405nm. Most laser goggles increase in visibility "slowly" and will filter to a lesser degree wavelengths close to the ones they are designed to block.
If there's no reading on the LPM you can use them safely. BTW, don't point a high power laser through the goggles to test them (unless you don't mind damaging the goggles) - test with a <100mW laser of the same wavelength.
