Optical Surfaces Ltd (www.optisurf.com) offers a range of standard and custom Precision Flats up to 600mm in diameter manufactured of high-stability materials such as glass, Zerodur and silica.

Precision optical flats are versatile devices for measuring surface flatness of polished areas by determining the variations between work surfaces and the surface of the optical flat. Uses include high precision applications in astronomy, laser beam steering, inspecting gauge blocks for wear and accuracy and interferometric flatness testing of prisms, filters and optical windows.

A unique thermally stable manufacturing environment enables Optical Surfaces Ltd. to routinely achieve a surface accuracy of lambda/20 p.v. and surface roughness of 10 A rms on individual precision flats. Having established itself as a world leader in high precision flat measurement technology over the last 40 years, Optical Surfaces Ltd. is recognised as a premier global supplier by many leading research establishments and national standards laboratories. All precision flats from Optical Surfaces come with full quality testing assurance. Optics up to 450 mm diameter are provided with a Fizeau interferometric test report, larger flats are quality assured using the Ritchey-Common test procedure.
