How good are RGB laser goggles?

[Apocalypse]

Hello all,

I see Laser Safety Goggles RGB goggles.

Are these safe for the high powered lasers we have for say.. 1W? Also, how do these work? Laser goggles block light at a specific wavelength. So for example, red rated goggles block at 630nm-~700nm and allow the rest through so they look blue. Do these block light at the common laser wavelengths (405nm, 445nm, 532nm, 630nm-660nm) and allow the others through?

Thanks!

They are not very good, usually they are great at block two wavelengths, and not so good at block the other one. When they do block all the wavelengths well then you can't see much because of the low VLT

The best full-spectrum (RGB) laser goggles can be found here. Made of solid stainless steel, they block tens to hundreds of watts across the entire visible spectrum. If you keep them in the refrigerator, they'll be more comfortable on your face when bombarded with high intensity beams.

I don't think that's what you're after though. One of the more important aspects of laser safety goggles is what you can see. I've stopped using certain pairs of goggles simply because they're too hard to see anything else with.

Any "RGB" goggles will either block too much light, or block too little. Neither situation is good. The closest thing I have to RGB goggles are ML7 goggles that work for 532nm, IR, and low-power red. They are a real pain to use for general work, so I generally don't use them anymore. Better to buy and some goggles specific to the wavelengths you want to use so that you can actually do other things while wearing them (like alignment, or even exiting the room).

If you want to cover most of the visible wavelengths you'll encounter, you can do well with a pair of ARG-filter goggles (532nm down to 405nm) and something like the RB2-filter goggles (red wavelengths). They don't have to be those specific goggles or brands, but something like that.

Well I already got an ARG filter one and a red one and was just wondering if there's a better one lol xD. I guess the more specific the wavelength the lower the visible light transmission. I wonder what the OD rating is on those stainless steel one...

No, usually the more specific the wavelength, the greater the VLT because all the other wavelengths aren't being filtered. You're pretty hooked up as is so I wouldn't bother with any broad spectrum goggles unless you're hanging out in white laser beams or something.
