High magnification of small diameter laser beams

Optical Surfaces Ltd. has developed a proprietary artifact suppression method allowing them to design and produce a novel high magnification reflective beam expander for small aperture laser applications. Accurate high magnification of small aperture laser beams has traditionally been a challenge because the optics associated with such a beam expander are difficult to test using an optical interferometer. This is because small aperture laser beams, when highly magnified, generate artifacts...

High resolution imaging of astronomical objects

Optical Surfaces Ltd reports that it has received a follow-up order from Magdalena Ridge Observatory (MRO) to produce three second generation off-axis beam compressors to expand the capabilities of the facility's optical interferometer. The Magdalena Ridge Observatory Interferometer (MROI) project's mission is to develop a ten-element imaging interferometer to operate at wavelengths between 0.6 and 2.4 microns with baselines from 7.8 to 340 meters. The technical and scientific goals of the...

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...

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...

Advanced instruments for performing accurate lens measurements

Optical Surfaces Ltd. reports how high precision off-axis parabolic mirrors it is supplying to OPTIKOS Corporation (Wakefield, USA) function as key components for collimation in their OpTest® product line of MTF measurement devices. Founded in 1982, OPTIKOS Corporation is a leader and pioneer in lens and image testing, and their products and systems are based on over forty years of experience and innovations in optical engineering. While other suppliers compromise by manufacturing their...
