Optical Surfaces Ltd. is a leading supplier of ultra-high precision optical flats to research establishments and national standards laboratories worldwide.
Using highly stable optical materials such as Zerodur®, and benefiting from a thermally stable production environment, Optical Surfaces routinely achieves surface accuracies of better than ʎ/20 peak to valley and surface roughness of less than 10 A rms on optical flats up to 600mm in diameter.
A 475mm diameter optical flat used as a reference surface to check the accuracy of the integration of
the main mirrors in a satellite payload structure.
Dr Aris Kouris of Optical Surfaces commented “Our optical flats provide extremely flat reference surfaces to test the surface accuracy of other optics including windows, laser mirrors, prisms, and filters”.
All optical flats from Optical Surfaces Ltd. come with full quality testing assurance. Flats up to 600 mm diameter are provided with a Fizeau interferometric test report, larger flats are quality assured using the Ritchey-Common test procedure.
