Zero Expansion Invar Alloy "IC-LTX" for Extreme Cold Resistance

Zero inverter usable at -100℃! Suitable for astronomical observation satellites, infrared telescopes, and other aerospace applications.

"IC-LTX" is a zero-expansion alloy for astronomical observation satellites. The mirror surface is constructed with a "ClearCeram-Z EX" structure, made from a super-invar IC-LTX material with an extremely low thermal expansion rate of <0±5×10^-8/K, achieving thermal dimensional stability and low-temperature resistance. The mirror surface and telescope structure are maintained at approximately 5°C to facilitate adjustments on the ground. The panels surrounding the telescope's 6A surface are temperature-controlled, maintaining the temperature during a half-orbit (50 minutes) with an accuracy of ±0.1°C. [Features] ■ All-metal structure designed for extreme low temperatures, providing stability and high feasibility of design values. ■ The mirror surface and telescope structure are maintained at approximately 5°C to facilitate adjustments on the ground. ■ Temperature-controlled panels surrounding the telescope's 6A surface maintain the temperature during a half-orbit with an accuracy of ±0.1°C. ■ The detector is cooled with a Peltier element, keeping it below 180K. ■ The high-temperature section of the Peltier is connected to a radiator via a heat pipe for heat dissipation. *For more details, please refer to the PDF document or feel free to contact us.
