Imaging spectrometer having a wide spectral range

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