Optical Surfaces Limited

A new 600mm Fizeau interferometer has been developed by Optical Surfaces, enabling it to now offer high quality testing of flats in a single aperture up to 600mm in diameter. This is a capability that only a few optical testing and manufacturing centres around the world possess.

  The supplier of ultra-high precision Etalon plates for use in Fabry-Perot interferometers is Optical Surfaces, which provide the etalons as standard in materials including UV grade Silica and Germanium. Etalons are available in two basic forms, air-spaced or solid.

Optical 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.

The OS-Z range of mirror mounts from Optical Surfaces Ltd. provides ultra stable, stress-free mounting and rapid alignment of off-axis parabolic, spherical and flat mirrors as well as wedge back and parallel back mirrors.  Constructed in black anodised aluminium, six models of OS-Z mount provide a secure, stable and compact platform for mirror diameters ranging from 90 to 250mm.

Optical Surfaces Ltd. has received a sizeable order from the Culham Centre for Fusion Energy (CCFE) to manufacture the relay imaging reflective optics that will form part of two critical viewing diagnostic assemblies for the Joint European Torus (JET) when operating with a deuterium-tritium fuel mixture. The project is funded under the framework of EUROfusion.

Optical Surfaces Ltd. is a leading supplier of laser debris shields (also known as protective windows or cover slides) to protect target-facing optics located in high-power laser facilities.

The production team at Optical Surfaces has manufactured a very fast parent F 0.6 parabola from which 3 fast focusing off-axis parabolic mirrors with surface accuracy of better than lambda/8 P-V, surface quality of 20/10 scratch/dig and surface slope error of lambda/10/cm P-V were produced. The world class Gemini laser based at the Rutherford Appleton Laboratory, delivers Petawatt power laser pulses to targets only a few microns in size.

Optical Surfaces Ltd. has delivered three challenging off-axis parabola of 175mm diameter to the UK's prestigious Rutherford Appleton Laboratory.

Optical Surfaces Ltd. has supplied the Laboratoire d'astrophysique de Marseille (LAM) with polished substrates to manufacture the high precision grisms that lie at the heart of a Near Infrared Spectrophotometer designed to perform red shift measurements in the forthcoming Euclid space mission by the European Space Agency (ESA).

Optical Surfaces high precision, large diameter spherical mirrors are used in a widevariety of applications including Schlieren imaging, wind tunnels, observatory spectrographs, bubble chambers and to test hyperboloids (as Hindle spheres).

In addition to supplying a range of standard specification Off-Axis Paraboloids (OAPs), Optical Surfaces Ltd. offers a consultative design and manufacture service to produce custom OAP's to fulfil the most demanding and specialist applications.

Optical Surfaces is a leading supplier of large, high precision reference flats and mirrors (coated flats) to research establishments, high power laser facilities and organisations worldwide

Ultra-high precision optics are useless unless they are positioned with absolute precision and stress-free. To fulfil this need, Optical Surfaces Ltd designs and manufactures mounts specifically for use with parabolic, spherical and flat mirrors to optimize the optical performance of optical systems.

Optical Surfaces Ltd has signed an exclusive distribution agreement with Laser 2000 GmbH to help expand sales and local support for its high precision optical components, mounted optical components and systems.

Optical Surfaces Ltd. has received an order from the STFC Central Laser Facility** to supply 6 Motorised Beam Reducers for one of their high power laser target areas (Target Area West) on the Vulcan laser facility.

Using proprietary production techniques - Optical Surfaces Ltd has established itself as a market leading supplier of demanding aspheric parabolic mirrors with off-axis angles approaching 30 degrees and focal lengths as short as 100mm. 

Working with a comprehensive inventory of advanced testing techniques, Optical Surfaces can produce both Plano-convex and Plano-concave toroidal mirrors in a range of shapes (largest dimension up to 400mm) with high performance and durable optical coatings that provide superior image quality.

An optical mount design service, delivering an optimised solution for a range of applications, has been introduced by Optical Surfaces. Typical custom modifications include mounts for non-circular optical components and for supporting larger diameter optics (> 600mm). 

Optical Surfaces has announced a new technical datasheet describing its range of standard and customer specified off axis paraboloids. Off-axis paraboloids provide an unobstructed aperture allowing complete access to the focal region as well as reducing the size and minimising the weight of a design.
