OPTICAL TELESCOPE OF REMOTE SENSING OF EARTH HIGH RESOLUTION FOR SPACE OF MICRO CLASS Russian patent published in 2018 - IPC G02B23/06 G02B17/08 G02B7/182 

FIELD: optics.

SUBSTANCE: telescope contains mirror-lens axial lens with non-circular aperture, including collecting input lens, in the center of which there is convex secondary mirror, concave main mirror-lens and prefocal two-lens corrector, and optomechanical design. Image plane is located near the rear surface of the main mirror fixing system. Corrector is located in the center of the main mirror-lens. In the main and secondary mirrors there are internal blends. Optomechanical design contains side racks, frame, holder placed on it, inside of which corrector is placed, and on the outside main mirror-lens and lens hood are fixed. Assemblies of the input lens with the secondary mirror and the main mirror-lens with the corrector are connected by side racks fixed on the side of the main mirror-lens on the frame, and from the side of the input lens on its holder. Secondary mirror is fixed to the input lens by means of the secondary mirror holder and its lens hood. Photodetector is fixed to the outer end of the holder of the main mirror-lens.

EFFECT: providing highly detailed cosmic survey of the Earth's surface when telescope is placed on the microclass spacecraft due to reduction of dimensions.
