Abstract: A spectrograph especially suited for research analysis of low level sources in such areas as reentry spectroscopy, comprising a high efficiency transmission grating or prism combined with a simplified Maksutov optical layout, and featuring lightweight structural components and arrangements which minimize thermally induced misalignments and simple adjustment mechanisms for focus of the film surface and alignment of the optical elements.
