Fellow Laserists,
Can anyone that is lucky to have a Spectrometer and a set of Barr & Stroud General Purpose Laser goggles, produce a graph showing the exact spectrum and OD of these goggles?
I purchased an Arctic and these goggles seem HIGHLY effective at virtually blocking the blue 445nm suggesting a very high OD but me being VERY safety conscious needs scientific verification.
I bought 2 pairs of these fantastic ex-military googles on ebay a few years ago for $40 for protection against 532nm.
From what I understand, they have a very wide protection covering several wavelengths including IR but like I said, I need to see a graph of this again......seen a specrograph years ago for these goggles but lost it.
Many thanks for your help folks.
