Subject: UV protection & spectra tubes
All,
Several years ago, I put several types of lenses (safety glasses,
goggles, and my eye glasses) in our UV-Vis spectrophotometer to see how
well they absorbed UV. The results I got showed high UV absorption and
were consistent with the manufactures' claims for UV absorption. The
exact results are lost in time somewhere.
The glass of the gas discharge tubes (If they are glass.) should absorb
much of the UV too. Thats why UV cuvettes are made out of quartz.
Could anybody check with a UV meter?
We can't weld with clear glassees because the visible and IR would also
damage the eyes.
