KENLEY, England, Feb. 3, 2012 — OS mounts from Optical Surfaces Ltd. are designed to support mirrors such as off-axis parabola, spheres and flats in applications where stability is important. Constructed in black anodized aluminum, four models provide a secure and stable platform for mirror diameters from 100 to 254 mm. Angular alignment can be made around two axes via dual-action adjusters with fine-screw and ultrafine differential micrometer action. A mirror can be aligned within a few arcsec. Each mirror mount is supplied with a baseplate to facilitate rapid mounting onto an optical table or other support. For larger mirrors in applications where pointing stability is important, the robust OS 260-600 series mounts are available in four standard sizes with optical apertures from 260 to 550 mm. To ensure operational versatility and flexibility, all mirror mounts provide precise micrometer screw adjustment around the vertical and horizontal axes. Various motorized mount options are available to suit applications in hostile environments or in places where limited space makes manual adjustment difficult.
