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 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) ... Read More Affordable, High Performance Beam Collimators Optical Surfaces Ltd. announce a new series of high-performance beam collimators designed for Modulation Transfer Function (MTF) testing of optical systems. Benefiting from a lightweight design and new assembly technique - the LW-series of beam collimators uniquely combine high stability, high performance and short delivery time all at a market competitive price. LW-series beam collimators incorporate a low expansion off-axis parabolic mirror, manufactured to better than lambda/10 p-v surface accuracy. The optics ... Read More Speciality Prisms for Cryogenic Measurements of Refractive Index for ESO ELT's Spectrograph - HARMONI Optical Surfaces Ltd has received an order to supply the University of Oxford, UK with 3 speciality glass prisms for a study that will enable defining key components in the state-of-the-art HARMONI spectrometer being developed for ESO's Extremely Large Telescope (ELT). The ELT, a flagship project of the European Southern Observatory (ESO), will be the largest ground-based optical telescope ever built. Located in Chile, with a primary mirror of 39m diameter, ...
