Context

Country: Unknown
State/Province: Unknown
Period: Unknown
Canada: Donated by McGill University in 1969, specifically Professor Nemec. Could have been used in their various research departments.
Function: Machine used to produce gratings on various surfaces in order to measure the absorption lines of different spectra. A sharp cutting tool (usually a diamond blank) would be dragged across a grating blank to cut a groove.
Technical: Blanking carriage moved across gratings due to the guidance of a well-made lead screw. Since larger gratings permitted higher spectroscopic resolution, the ruling engine was designed to groove larger spaces. Temperature and environmental control could be incorporated, as well as kinematic isolation.
