Optical Design of a Multi-Spectral Imager for LWIR

Abstract

The task of this study was to create an optical system that creates an image on 16 separate sectors of a bolometric detector. The aberration of the far-infrared multispectral camera has been minimized. We developed a layout of a multi-spectral camera in the range of 8-12 microns that provides sufficiently high quality of spectral images in the entire range. Aberrations are minimized in the ZEMAX program using the procedure for optimizing the geometric parameters of the optical elements of the circuit.
