Abstract
This applies to the design of a telescope system imaging spectrometer, imaging spectrometer for the characteristics of the telescope from the pre-and post-spectrometer components. Pre-telescope system parameters and imaging quality of the application of the imaging spectrometer is very important. This paper designed a spectral range of 1000nm ~ 2500nm, field of view of 28.1 ° × 0.3 °, a relatively large diameter of 1 / 4, 180mm focal length of the telescope system. Systems in a wide spectral 1000nm ~ 2500nm spectral range by the glass and two matching spectral correction of chromatic aberration, distortion control at 0.2%, to ensure good follow-up spectroscopy with the butt, this design can be used for aviation the large field, high-resolution imaging.
