High-precision ellipsoidal mirrors
Optical Surfaces has announced its precision ellipsoidal mirrors for demanding applications in telescopes, beam expanders and high-resolution x-ray imaging instruments.
Ellipsoidal mirrors are the optical component of choice in these applications as they efficiently refocus the light from one focal point to a second without the need for additional optical components thus allowing for a more compact optical system.
Optical Surfaces routinely produces ellipsoidal mirrors in a range of materials (Zerodur, BK7, fused silica) with typical surface accuracy of better than lambda/10 (dependent on size and radius) and surface quality of 20:10 scratch dig.
Dr Aris Kouris – Sales Director at Optical Surfaces commented: “In addition to supplying batches of coated ellipsoidal mirrors to a leading instrument manufacturer we also produce one-off and prototype ellipsoids in a range of shapes (largest dimension up to 650mm) that offer high performance and excellent image quality.”
