Re: GB for OEM Laser Systems protective eyewear
There is only one filter available that is true broadband. It will protect you against all visible, UV and IR lasers at any power. Of course the VLT is 0% but the OD is 10+. They are stainless steel eye cups used by patients of doctors and dentists who operate laser systems.
You have to remember, the filters that have been developed have not and will never be developed for the hobby community. Even the junk Chinese filters were used elsewhere before making their way to the hobby. You can get custom filters for about any wavelength and OD you want, and we can get it for you, but I doubt anyone would be willing to pay to have that done since there is such reluctance to buy even existing protection.
I personally don't see the use after seeing these specs... or at least if they're true and not omitting anything important

The ML7 for the hobby meets the protective needs for a few wavelengths common for pointers but in the industry they are unparalleled for those who work with open resonator YAG systems that need to be aligned. They protect against 532nm for doubled YAG, they protect against 808nm and 980nm for pump diodes and against 1064nm and other YAG wavelengths. The red protection allows alignment OD for aligning the optics train of YAG systems using a red diode laser or HeNe laser.
You won't find any other broadband goggles that protect at specific wavelengths across the visible and IR spectrum like the ML7. It's not the most ideal but it's the best available for those hobby wavelengths.
As far as what is true or not, we are absolutely forthcoming about the safety systems we offer and we have the certification documents to back it up. We also have the trust of the U.S. and Canadian governments as well as many university and national laboratories. Their laser safety officers seem to think our filters are pretty good.
Personally, I'm glad to see interest in safety systems as I believe it is important. With that said, however, do your homework. If you buy from us, that's great, we welcome you as a client but if you don't, just make sure you get something that is certified. Armchair analysis is no substitute for real standards testing.
Here's a gee-whizzer about the ARG filters: We have 3 or 4 pair in our lab. We use them for all blue and green to 532nm including pulsed systems. My pair is the ARG #34 style.
