RESEARCH, DESIGN, AND FABRICATION OF AN IMAGE TUBE FOLDED SCHMIDT SPECTROGRAPH.
Abstract
A spectrograph has been designed and constructed that will accommodate either the RCA cascaded image tube or an electronographic image tube if the photocathode can be operated near ground potential. The spectrograph is a grating one with an on-axis collimator, pierced grating and Schmidt camera. The complete spectrograph body is cradled in a frame that attaches to the telescope. The dispersions are 50 and 100 A/mm. (Author)
