About
These Aspherical Monolithic Mirrors are designed to serve as a complete set of objectives for Optical-Electronic Complexes (OEC), commonly found in space telescopes or other optical instruments. Manufactured since 1998, they boast a production/delivery time of approximately 9 months. While the product itself does not have direct flight qualification, it has been contained within a customer’s apparatus that has achieved flight heritage. The manufacturer offers the possibility to adapt the product to specific customer requirements. Key features include the use of material with extra-low Coefficient of Thermal Linear Expansion (CTLE), specifically Sitall CO-115M, and significant lightweighting up to 70%. The mirrors possess an aspherical rotation surface and incorporate glued interface elements. They achieve a high surface quality with an RMS of reflected wavefront less than 30 nm, and are finished with a reflective coating of Al+SiO2. The item is produced in accordance with the Customer’s working design documentation (WDD).
