Abstract: An interchangeable encoding cassette and a spectrometer system employing such cassette, which cassette device encodes the spectral energy of radiation at the exit focal plane of a spectrometer, the spectral energy represented by horizontal and vertical components. The cassette device comprises a rotating encoding disc, a stationary aperture plate, a frame element, and a shaft secured to the encoding disc for rotation therewith. The frame includes bearings on which the shaft is mounted and includes a reference pin. The spectrometer includes a pair of locater mounts, each of which has a precision V groove adapted to receive the shoulders of the bearing element of the cassette, one of such locators having an adjustable track adapted to receive the pin element, whereby the shaft serves as a primary reference and the cassette device is adjusted into the desired precision position by the position of the reference pin in the restraining track.
