KENLEY, England, Dec. 7, 2011 — Working with high-stability materials such as glass, Zerodur and silica, Optical Surfaces Ltd. supplies high-precision reference flats.

Reference flats are a proven method of measuring the surface accuracy or the transmitted wavefront of flat surfaces or optics. Benefiting from a thermally stable manufacturing environment, the company achieves a surface accuracy of λ/20 peak-to-valley and surface roughness of <1 nm on reference flats up to 600 mm in diameter.

The reference flats are used in 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.

All are supplied with full quality testing assurance. Optics up to 450 mm in diameter are provided with a Fizeau interferometric test report, and larger flats and spheres are quality assured using the Ritchey-Common test procedure.
