Abstract

Surveyed are resylts of development, design, fabrication and thermal-optical test of optical mirrors out of vatious materials for space IR systems operating at cryogenic temperatures. Results are presented showing feasibility of optical mirrors having diameters to 900 mm and wavefront errors RMSWFE=0,05(lambda) (at (lambda) =200 nm) operating in systems and instruments at 10-15K. Results of thermal-optical tests are given.
