Goggles for 445nm AND 635nm

Roam · Jan 9, 2012

I’m looking for a safety goggles that I can use for both 445 blue AND 635nm red/orange. Most people in the forums seem to recommend the Eagle Pair goggles so I found this:

Eagle Pair® 190-470nm & 660-760nm Laser Safety Goggles

It says these glasses "have an OD of 2.5 at the 635nm" (as opposed to OD 4+). Is this a bad thing? Or is it still effective against both wavelengths (they are 1W and 400mW respectively)?

these goggles appear to have an OD of approximately 2.5 at the 635nm wavelength.

That should be fine for <500mW's of 635

I don't think you can go wrong with those goggles

I see. Thank you very much guys.

When the high-power 635nm diodes became available, I did some testing with these goggles. They seemed to pass more light than with the 660nm diodes, but i could not measure anything coming through them on my LPM. Out of an abundance of caution I changed our recommended nm range until more detailed testing could be completed. However, they should be fine for under 500mW of 635nm as noted by LaZeRz.

It's funny when they put "CE certified" when that can simply mean they're certified to be impact resistant or something entirely unrelated to laser protection.

A CE certification for laser safety glasses means it's compliant with EN207 or EN208 which have a typical rating.
