Latest News  High Precision Telescope Spectrograph OpticsOptical Surfaces Ltd. is a leading international supplier of high precision spectrograph optics for astronomical telescopes. Using a spectrograph enables researchers to study the chemical and physical conditions that exist through a cross-section of space. Combined with a land or space-based telescope a spectrograph can reveal valuable information from the spectral distribution of light from a distant astronomical object. Benefiting from a unique facility, where temperatures remain constant year-round and vibration ... Vacuum Compatible Beam ExpandersOptical Surfaces Ltd. (OSL) reports on growing demand for specialist Reflective Beam Expanders for high power lasers applications that can achieve higher power density through operating in a vacuum. Supplied optimised to individual customer specifications, all OSL vacuum compatible beam expanders incorporate smooth running mechanics that do not require lubrication, optical designs that avoid use of glues and cements that might outgas and sandblast finished metalwork that eliminates stray light without ... On-Axis Parabolic MirrorsOptical Surfaces Ltd. offers a complete manufacturing and test capability to produce On-Axis Parabolic Mirrors up to 600mm (24-inches) in diameter. All on-axis parabolic mirrors are manufactured to customer specifications and are supplied with full surface quality test data. Parabolic mirrors are the most common type of aspherical mirrors used in optical instruments. They are free from spherical aberrations, and thus focus the parallel beam to a point or point source ... High Performance Lenses for Wide Field ImagerOptical Surfaces Ltd. has supplied to the National Observatory of Athens (www.astro.noa.gr) a series of high precision lenses designed for a new state-of-the-art wide field imager that will extend the capabilities of its 2.3m Aristarchos Telescope. The Aristarchos Wide-Field Camera (AWFC) is a new state-of-the-art wide field imager** which will be used on the 2.3m Aristarchos telescope at the Helmos Observatory in Greece. It has a 26 x 26 arcmin field ... |
