Default Techhood laser safety glasses, any good?

I'm looking to buy another pair of laser safety glasses, but especially for 808nm. Has anyone purchased these or have an opinion, better glasses than these?

Professional 200nm 450nm 740nm 2000nm Laser Protective Goggles High Quality Lab | eBay

I wanted to do some optics tests with a FAP808nm IR laser tonight but dare not do it without glasses, my others are missing from my move to Alaska.

Sincerely investigate any of these three short quotes as new concepts and you've taken your first step into a larger world:

"I regard consciousness as fundamental. I regard matter as derivative from consciousness..." - Max Planck. "Everything we call real is made of things that cannot be regarded as real" - Neils Bohr. "What we call physical things and events do not exist independently of subjective experience..." - Deepak Chopra.

Each of these three rabbit holes go deep, ending up in the same place.

Default Re: Techhood laser safety glasses, any good?

They say they are CE certified, but I don't know if that can be trusted.

I wouldn't risk it with high power IR. Laserglow has ANSI and CE certified goggles, but they do cost a bit more: https://www.laserglow.com/AGF#
They offer a discount for LPF members, use the coupon LPFGOGS for 20% off.

Thanks, the prices at LaserGlow leads me to wonder how Techhood can sell their goggles at such a low price.

You have some others like these: http://www.aixiz.com/store/index.php...26c8c685088a56
or these: Eagle PairŪ 190-540nm & 800-2000nm Laser Safety Goggles
but at the power level your thinking about I would look around for something of the best quality you can afford.

Default Re: Techhood laser safety glasses, any good?

Pi beat me to it. The eagle pair will work, though you could spend more and get a pair for, NoIR LaserShields. I know for sure DBD filter would work, dunno the rest that cover the IR range without looking.

Default Re: Techhood laser safety glasses, any good?

Thanks, those glasses won't work for me because I need wear-over goggles so I can use my reading glasses under them. I'd like OD7 due to the 50W FAP 808nm lasers I have. In the past I wore OD5 when working with those lasers but would use my cell phone camera to look at the spot by always keeping the phone as a direct shield from it even then, this IR scares me. I might have to settle with OD6 808nm wear-overs, if I can even find them.

Default Re: Techhood laser safety glasses, any good?

No real use for IR, just a hobby laser I am interested in, originally, I bought them to use with a 12 inch beam expander for a mountain top to mountaintop telecommunications experiment at a very slow speed. Now, I'd like to photograph the beam of a IR laser straight up into the night sky (no airplanes present), but only if the beam is tight enough or has a low enough divergence (beam expander probably necessary), otherwise I don't think it will be very impressive.

EDIT: Not the OD6 I wanted for 808nm, but all I could find for now, bought them:
