I got my hands on these goggles from eBay and they are rated for 405nm, 445nm and 532nm. However, these goggles are not OD rated. I'm planning on running a few tests to figure out the percent of light penetration at these three particular wavelengths.

I fully understand and expect different level of light penetration at different light waves. The million dollar question is that the level of penetration is consistent at different power for the same wavelength. To clarify, if I shine a 100mW 405nm laser thru the goggles and the laserbee meter shows 5mW, then that is 5% penetration. However, when i shine a 500mW 405nm laser thru the same goggles, will I still get 5% penetration? and therefore 25mW?

If it is consistent, it'll make my life much easier. I'd just need to test a laser for each of the three wavelengths. Otherwise, it'll be a bitch to get a whole table of data in order to show the amount of protection the goggle offers.

Thanks

Yes, if you get a 5% pass at 100mW you will have a 5% pass at 500mW - at the same wavelength. You will need to test the wavelengths though.

My site has an OD calculator on the goggles item page - RadiantShades for Blue and Green Lasers

Nice tool, Mario thanks...
