Improving Alignment & Testing of Earth Observation Satellites

Optical Surfaces Ltd. has received an order from Surrey Satellite Technology Ltd. (SSTL) for two high precision reference mirrors to accelerate the precise alignment and testing of their Earth Observation Satellite Telescopes. Based in Guildford, UK, Surrey Satellite Technology Limited (SSTL) manufacture and operate small to medium sized satellites, covering a range of use cases, from telecoms to Earth observation. Earth observation (EO) satellites are a core product for SSTL and ...

Athermalised Beam Expanders for Challenging Applications

Athermalised Beam Expanders for Challenging Applications

For beam focusing applications in environments subject to wide temperature variation, Optical Surfaces Ltd. is able to produce athermalised beam expanders that deliver stable high performance. Optical Surfaces athermalised beam expanders are based upon a Dall-Kirkham off-axis mirror design that incorporates INVAR elements to provide thermal stabilisation. In addition, to better control thermal behaviour, the off-axis mirrors in the athermalised beam expanders have a short focal length resulting in a very ...

Beam Collimators for MTF Optical Testing

Beam Collimators for MTF Optical Testing

Optical Surfaces Ltd is a leading supplier of Beam Collimators tailored to enable precise Modulation Transfer Function (MTF) testing of your optical systems. MTF is a trusted technique for objectively evaluating the image-forming capability of optical systems. Reflective beam collimators are mirror assemblies that take divergent or convergent incoming light rays and produce parallel light output. They can be used to replicate a target at infinity without parallax. As a consequence, ...

Off-Axis Paraboloids Enhance Laser Power Density

Off-Axis Paraboloids Enhance Laser Power Density

Optical Surfaces Ltd. reports on increased demand from high power laser research groups around the world for off-axis paraboloid mirrors to be used as the primary focusing element for their Petawatt laser beam lines. Off-axis paraboloids offer the advantage of an unobstructed aperture and access to the focal plane. In addition, due to their completely achromatic performance, they are especially suitable for broadband or multiple wavelength applications. Using proprietary production techniques, and ...
