Abstract

Lenses or mirrors are formed from a substrate (2) which is exposed in a controlled manner to a source of molecular flux (3). A rotary disc aperture (12) contains a circular aperture (13) which increases in radial extent around the disc. The disc (12) is coaxial with the exposure source (3). The substrate is carried in an orbital rotor (5) which is precessed around the aperture track by a mechanism of gears driven by a motor (10) and carried on another coaxial rotating table (9) driven by motor (11). The exponential form of exposure to the evaporating molecular flux forms the desired lens or mirror characteristics in the substrate (2).
