Vintage Goggles
Here's a really nice pair of goggles I just received into the archive. Made by Spectrolab for visible lasers, they were calibrated 50 years ago, on the exact date they were received here. Although one filter is chipped and there is terrible crazing on both of the rear elements, they are in generally good shape. Another great artifact for the collection.
Two other styles of goggles from the period are shown below, both from American Optical.
