Default DX Safety Goggles 610-700nm

Does anyone know if the DX laser shades that protect you from red lasers are reliable? I love the way it looks :P, but since it is from DX, I'm not sure how good the quality would be.

Default Re: DX Safety Goggles 610-700nm

From what it says in the description, it reduces transmission by 100 times at 632.8nm which would be OD2. It will most likely be around the same for the rest of the red zone it covers. Of course, like you said it is from DX so I may very well be completely wrong. A general rule when buying glasses is to reduce the transmission to 5mW or less for whatever power you are using. For example, if you have a 300mW red and you want no more than 5mW to reach your eye if it happens to point there, you would need a factor of 60 reduction which is OD1.78. These therefore would be OK provided they are actually OD2 for reds up to 500mW. Anyone correct me if I'm wrong of course.

I wouldn't trust my eyes with DX :P If you are looking to get some goggles for red just buy them off of shop.stonetek.org

Yeah that too. Doesn't he have multi-band goggles too that cover most of the lasers most people will ever use?

The 600-700nm protective glasses are not certified. The 200-540nm from this manufacturer are CE certified as well as the 800-1100nm and 200-540nm, 800-1100nm glasses in OD4 for all three types of glasses.

So it would be a safe thing and stay away from these right?

Default Re: DX Safety Goggles 610-700nm

The safe thing would be to acquire protection that is certified by the FDA or CE equivalent to insure you have the necessary protection for a direct exposure. As I mentioned, the other wavelengths are CE certified just not the 600-700nm.
