Abstract : The Monolithic Optical Programmable Spectrograph (MOPS) is a rugged, vibration resistant, inexpensive, compact spectrograph. It is capable of simultaneous multi-channel measurements of wavelengths and bandwidths of sources in the visible light and near infrared spectrums and has a resolution more than sufficient to resolve the near infrared 1060 nm wavelengths in the first order from the optical wavelengths 454, 472, 488, 496, 514, and 532 nm in the second order. The MOPS has sufficient linear space at the exit focal plane to accommodate a standard linear diode array package. This means that the wavelength dispersion is sufficient so that the wavelengths of interest are spread over about two centimeters. The spectrograph uses a grating with a large number of grooves/mm blazed to scatter light in second order. This enables the spectrograph to be smaller by a factor of two than if the grating were operating in the first order. The MOPS utilizes the favorable geometry for the spectrograph that is afforded by the Czerny-Turner geometric configuration. It is constructed by BK7 optical glass for rigidity.
