Default Which glasses for 650nm 200mw?

Hello, i have on order a 650nm 200mw pocket laser from Sanwu. I was wondering what glasses to get. i wear prescription glasses so the larger goggle type would be ideal. I looked on eagles website but they have ons that range up to 640 but not 650 or 800+. is 650nm not as hazardous?

Default Re: Which glasses for 650nm 200mw?

I have a pair of these from Survival Laser, they work well in that range, but they unfortunately are not slipover style for prescription eyeglass wearers.
I wear prescription glasses myself, and I put these over my glasses, they work, but they don't fit near as well as dedicated slipover style glasses.

Edit: A while back, I had asked Gary at Survival Laser about carrying a slipover style for this part of the spectrum, but at the time he couldn't get them.

650nm is just as hazardous as all other visible wavelengths.

Cool, thanks. I'll have to graba pair. Curious question, how dangerous would it be to shine a 250mw 650nm laser in a basement at a concrete wall. not reflective at all. Without glasses?

What's the distance between your eyes and the wall?

Jhop, I forgot to mention in my last post that Survival Laser has a 10% discount for LPF members; it's LPF445 I believe.
