Lens of optical scanner of microsatellite of 12U format contains front compensator, primary and secondary mirrors and rear compensator. Note here that front compensator has one input lens 1 that is positive and shaped to meniscus. Primary mirror is made as Mangin mirror (2) in the form of meniscus. Secondary mirror 3 is connected to front compensator input lens 1. The rear compensator consists of two lenses: the first lens (4), which is positive, and the second lens (5), which is negative.

The useful model belongs to the field of optical devices of small size, namely to the field of optical scanners of remote sensing of the Earth, and can be used to solve the problems of obtaining high-quality images when monitoring the Earth’s surface from high altitudes.
