PRODUCTION OF FLAT OPTICAL ELEMENTS FOR MILLIMETRE AND SUBMILLIMETRE RANGES ON COMMERCIAL NUMERICALLY CONTROLLED MACHINES
E. D. Bulatov, S. A. Gridin, A. A. Danilenko
Consideration is given to the issues arising in the production of flat optical elements for millimetre and submillimetre ranges on commercial industrial machines with numerical control. A method for the production of flat optical elements on a numerically controlled turning machine is described, together with the appropriate algorithm. Much attention is paid to the technical details of making a cylindrical lens on a numerically controlled milling machine. Methods enabling the production of flat optical elements with specified accuracy on such a machine are described, as well as algorithms for control programs. The flat optical elements produced by these methods on commercial numerically controlled machines are briefly described.
