Satellite IR imaging spectrograph is composed of middle- and LWIR imaging thermal imaging smodule and multi-spectrum IR optical system, covering spectral imaging thermal imaging module, MWIR cooled detector, LWIR cooled detector, imaging measurement circuit, driver control circuit, filtering module and anti-irradiation structure. The spectral response ranges are 3.7μm~4.8μm and 7.7μm~9.5μm. multi-spectrum imaging can be realized by a dual-band IR optical lens introducing the narrow band filter of the optical system.

The product adopts non-uniformity correction, blind pixel compensation, image filtering, image intensification, linear stretching, automatic dimming and other intelligent image processing algorithms, to ensure good image quality and characteristic measurement. Characterized by high sensitivity, easy integration, multiple interfaces, high reliability and strong expandability among others, the imager can work around the clock.
