Silicon carbide specimen at MILEX 2023 exhibition in Minsk.
Holding Shvabe (part of the state corporation Rostec) at the international arms exhibition MILEX-2023 in Minsk presents a mirror made of superhard silicon carbide and optical glass-ceramic – a material for mirrors of optoelectronic systems for remote sensing of the Earth (ERS).
This was reported to TASS on Wednesday by the press service of the holding company.
“A lightweight silicon carbide mirror, created at the Lytkarino Optical Glass Factory, is displayed at the Shvabe stand. The material has high specific stiffness, strength and thermal conductivity. Such properties of silicon carbide make it possible to create lightweight space imaging equipment on its basis, which can even be installed on small satellites. Thanks to silicon carbide materials, optical equipment for space becomes more durable and virtually insensitive to changes in ambient temperature“Shvabe said.
In addition, visitors to the exhibition can see a high-strength optical assembly used to create mirrors for optical-electronic remote sensing systems, large ground and space telescopes. As noted, the use of ceramic glass can reduce the weight of the finished product by 50-80%.
Visitors to the exhibition will also be able to get acquainted with the SWIR camera operating in the short-wave infrared range (short-wave infrared range, SWIR), which makes it possible to observe objects in difficult climatic conditions and limited visibility, for example, through smoke and fog.
Silicon carbide is an extra-hard crystal with very high thermal, chemical and radiation resistance. It is one of the most promising composite materials for the production of optical devices operating under conditions of extreme temperature fluctuations.
