High precision ellipsoidal mirrors

High precision ellipsoidal mirrors

Optical Surfaces Ltd is a leading manufacturer of 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 ...

Optical Surfaces expands range of large diameter mirror mounts

The OS series of large-diameter mirror mounts from Optical Surfaces Ltd. are proven to provide a secure platform for larger, high-precision flat, off-axis, and spherical mirrors in stability-critical applications. Manufactured in robust, black anodized aluminium, OS series mounts have traditionally been available in four standard sizes to accommodate mirrors up to 300mm, 400mm, 500mm and 550mm diameter. The new OS350 and OS450 mounts provide researchers with a smaller and lighter stable ...
