A Vacuum Spectrograph for the Infra-Red
Abstract
A description is given of a 1-meter focus vacuum grating spectrometer for the infra-red which is distinguished by its versatility and compactness of design. The vacuum container is tubular in form and all optical parts are mounted on a carriage which is readily retractable from the case for adjustment. A novel feature is the use of a sine screw drive which gives a linear wave-length scale. A representative spectrum tracing is given.
