ABSTRACT:
A compact, lightweight, yet sturdy imaging spectrometer, especially for use in satellites, flying bodies and the like, has elliptical mirrors for its objective or lens, for its collimator, and for its imager. The collimator and imager are formed by the same mirrors which reflect the beam twice. The optical arrangement of the objective or lens, the collimator, and the imager is such that any bending of an object strip by a diffraction lattice or grid is compensated. Such a spectrometer is usable for a wide field and wide spectral range, including the non-visible range.
