image.jpgI'm using a Phillips glasblowers lens. Didymium glasses.

This is the filter specifications they state at there website.

It's been a while since I did a quick analysis and I'm no expert. But as I can see it these lenses filter UV A, B and C and of course sodium flare. I don't know how it relates to the shading of green welding glasses.

I'll post a spectrum of AO welding I've found in a uni paper when I've found it on my computer.
