PARABOLOID FOCUS

Off-Axis Parabolic Mirrors (Paraboloids)

Off-Axis Parabolic Mirrors (Paraboloids)Unlike standard parabolic mirrors, Off-Axis Paraboloids (OAP) direct and focus incident collimated light at a specific angle, allowing unrestricted access to the focal point as well as reducing the size and minimising the weight of an optical design.

Beam Compressor for Magdalena Ridge Observatory Interferometer

Beam Compressor for Magdalena Ridge Observatory Interferometer

Optical Surfaces Ltd. has been selected by the Magdalena Ridge Observatory (Socorro, New Mexico, USA) to produce an ultra-stable 7.5x off-axis beam compressor that will form a key beam transfer element in the facility's optical interferometer. When completed the Magdalena Ridge Observatory Interferometer (MROI) will be one of the world's most powerful optical-infrared interferometers, dedicated to high resolution imaging of all types of astronomical objects. The objects that will be observed ...

Challenging Aspheric Lenses for Nuclear Research

Challenging Aspheric Lenses for Nuclear Research

Optical Surfaces Ltd announces that it has received an order from the UK Atomic Weapons Establishment (AWE) for twelve ultra-fast focusing 370mm diameter aspheric lenses for its Orion petawatt laser research facility. World-class expertise and cutting-edge science, engineering and technology lie at the heart of AWE work, spanning the life cycle of nuclear warheads from initial concept and design, to final decommissioning and disposal. The Orion laser facility is used to conduct ...

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 ...

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 ...
