Developing and fabricating optical systems for a prospective remote-earth-probe spacecraft

Abstract

This paper presents specific examples of the fabrication of the APO Zenit-GL and APO Zenit-GTs high-quality apochromatic objectives, used in the Gamma-L and Gamma-Ts space-based optoelectronic complexes, along with the design of a high-accuracy spectral-beamsplitter prism module. The use of compact mirror-lens optical systems with eccentrically arranged image fields is also considered, and this in turn makes it possible to substantially reduce the mass of the apparatus and creates a fundamentally new class of compact systems for remote probing of the earth.
