Abstract
The infrared dual magnification telescope for 8 to 12 micron wavelength region is designed. The optical system consists of five lenses and has a high transmittance. The switching of magnifications implements with movement of one of lens along an optical axis. The diffraction optical element is used for chromatic correction. Thermal correction is made with movement of two lenses with the help of two electromechanical drivers.
