survival lasers is kinda sketchy about ratings. some are straight up lies and theres a lot of inconsistency in the coverage. I wouldn't trust my eyes with SL for anything over half a watt never mind 7 watts of 450.. I'd go for OD7 190-532nm from Laserglow https://www.laserglow.com/product/AGF-Laser-Safety-GogglesHello! I'm just wanting to make sure that I dont burn out my eyes while testing my diode. Its the Nichia Nubm44 7W 450nm laser module, and the goggles are the survival laser Eagle Pair 190-540nm OD6 slipover goggles. Thanks!
they can do good but, theres been some recent tests where the OD below OD3 for OD6 rated goggles and the 15-4 IR goggles dont even reach OD 1 for the MAIN yag wavelength... they can do good but the inconsistency and lies about specs make them untrustworthy. its ultimitely up to you if you want to take that risk and trust them but personally, i wouldn't. styropyro actually removed his video recommending them so if that isn't proof enough, idk what is. there also graphs and convos in the survival laser open thread but thats kind of a trainwreck right now with the owner being super sketchy..Really? I've seen a few videos of Eagle Pair glasses being great.
thats not the proper way to do it. first off, you'll ruin the goggles before your power meter has time to measure them, and the OD increases dramatically as they char.. even at low powers, you won't get an accurate reading. you need a proper spectrophotometer. and i'm guessing this guy doesn't have a LPM even if he wanted to do a sort of sanity check.Shoot the laser through them and measure what you see on the other side. No lies or false promises when you do that
when I say see I mean with a power meter! Not your eyes. Also don’t expect them to survive long term with full power focused on them. They likely will melt. Shoot say 100mw and measure that. They are not meant for prolonged blocking.
and yea they generally are good for blue but, why risk it? im not saying they've failed for blue but, i'm saying they've failed for yellow, green, IR in the past and they're still being listed as OD 4, 5, 7.. i wouldn't trust my eyes with that brand.Which Eagle Pair are you looking at? The ones I have protect extremely well in the blue spectrum.
