Description

This item is a metal box with a removable lid.

This light-tight film cassette was used with the precession camera (IN-1257). Precession cameras were used to take x-ray diffraction pictures of a crystal. MIT professor Martin Buerger first conceived of the device in 1937, and working with his machinist, Charles Supper, the two men collaborated on its manufacture in the early 1940s. The Buerger-type mechanical precession camera became the standard instrument for creating x-ray diffraction images until the 1980s.
