Brazing or Cutting Goggles?

Question

I have a pair of brazing goggles with a #6 shade in them. I would very much like a spectral graph for them. I'm interested in their wavelength absorption properties.

Answer 1

Try this:

search on "Welding Shades" in Table 1.  It lists the general spectral properties of a #6 lens.  

Here's the same information from a different source.

My hunch is that the "curve" would be relatively flat through the visible.  I would suggest using google/images and strings like "welding shades spectral curve" to track that down if you want more detail than what's above.
