10 November 1975Design Consideration For Intermediate And Far Infrared Optics
The paper deals with the optical design for the infrared region. The problems of different materials for the various IR regions are discussed, taking into consideration the refraction, dispersion and absorption losses, as well as the material deficiencies. Ways of measurements and the varying testing methods are analyzed. In addition to the basic optics, the Zoomar orbiter and two Zoomar IR lenses are described.
