OPTICAL COMPONENTS AND INSTRUMENTS		PARABOLOID FOCUS Off-Axis Paraboloids Enhance Laser Power Density Off-axis parabolic mirrors can be a useful tool in optical design. OAPs combine the achromatic and diffraction limited imaging properties of a parabolic mirror with the ability to deviate the light path off-axis, which is useful for most imaging systems. OAP’s offer the ability to focus collimated light without introducing spherical aberration. Continue…

Latest News Ultra-Stable Mounts for Optics & Mirrors Optical Surfaces Ltd offer a range of high precision mounts developed to support off-axis paraboloids, spheres and optical flats up to 600mm diameter in applications where stability is important. Constructed in black anodized aluminium – four models of OS Mounts provide a secure and stable platform for mirror diameters from 100mm (4 inches) to 254mm (10 inches). Angular alignment can be made about two axes by means of dual action adjusters ... Read More Light Weighted Mirrors Optical Surfaces Ltd has developed proprietary light weighting techniques that can reduce the weight of a mirror by as much as 60%. In spaceborne applications the need to minimise payload is a key factor in designing optical systems. Optical Surfaces lightweight mirrors are designed to provide sufficient rigidity to ensure ultra-high precision optical performance while reducing the overall weight of the mirror. This reduced weight, in turn, allows smaller, lighter support ... Read More Environmental Monitoring from the International Space Station Optical Surfaces Ltd. reports how a motorised UV-Vis-NIR collimator and interferometric alignment system it supplied to the Deutsches Zentrum für Luft- und Raumfahrt (DLR) in Berlin, Germany has been used to set-up the ground breaking DLR Earth Sensing Imaging Spectrometer (DESIS). On 23 October 2019, DLR the renowned German Aerospace Center, and the U.S. company Teledyne Brown Engineering (TBE) announced the start of routine operations for DESIS on the International Space ... Read More Spectrograph to Record Near-IR Spectrum of Stars in a Single Exposure Optical Surfaces Ltd reports delivery to the Research Institute in Astrophysics and Planetology (IRAP) of high precision disperser prisms and folding mirror components that lie at the heart of the ground breaking SPIRou / SPIP near infrared spectrograph. The SPIRou / SPIP spectrograph is designed to be able to record the whole near infrared spectrum of a star (over the wavelength range 0.98-2.35 µm and in either circular or linear polarization) ...
