Abstract
The optical design and the expected performances of a multi- band imaging system are presented. The instrument is to be operated in a low earth orbit in a pushbroom scanning mode. It has 15 spectral bands with the wavelength range extending from 0.45 micrometer to 10.7 micrometer. The instrument comprises a single mechanically cooled focal plane, a 36 cm aperture, wide field of view off-axis three mirror anastigmatic telescope, and an on-board calibration subsystem. The design has near diffraction limited performance for all spectral bands from visible to long wavelength infrared (IR). It has high throughput and low polarization sensitivity. To minimize the background noise at long wavelength infrared (LWIR) a cold stop is located at the exit pupil to achieve 100% cold shielding.
