Today was a very good day for the Vintage Laser Archive, as a c1963 Spectra-Physics model 131 he-ne laser head was added to the group. This is one classy little laser at about a foot long, and with the first version of the S-P badge in great condition. I love the complex plasma tube inside, with its multiple u-turns and glass support bridges. There are even a few magnets under the bore.
