Abstract. Methods of protection of space-bazed optical-electronic systems from meteoroids and space debris are stated. To create protective screens, it is proposed to use a new material - armored glass ceramics. Technical solutions (segmentation of mirrors, elongated hoods, transitional optical blocks) for the protection of optical elements are considered. The developed and manufactured setup for studying damage caused to the working surfaces of optical elements is presented. The setup allows to carry out ballistic impact by throwing elements of various masses and geometries. Results of experiments are presented.

Keywords: surface roughness, RMS roughness, optical element, optical surface, diamond micro turning, light scattering
