Re: Laser saftey eyewear (generally and specifically for Spectra Physics Millenia IIs)

Hi Adrian...

We just ordered some laser safety goggles from Trinity Technologies 
(http://www.lasersafety.com/).	Many different styles, wavelengths and 
absorption levels available.  The standard orange ones should work for 532 nm.

P.S. I have no commercial relationship with this company - just sharing a 
source for a surprisingly hard-to-find item.
