Commercial Applications of Precision Manufacturing at the Sub-Micron Level | 1992

Computer-controlled polishing to fabricate special optics

Volkmar Giggel; Armin Leitel

For high-resolution optical imaging systems used in photolithography, lenses with diameters up to 200 mm and surface accuracies of about 25 nm are required. To realize an economic production of such elements, a computer-controlled polishing following classical techniques has been developed. Applications in the laboratory and production spheres are presented for components made from Zerodur, optical glasses and calcium fluoride.
