Development of new production technologies for optical components with spherical surfaces
Abstract
Spherical surfaces for precision optical components were produced by a two-step method instead of the three-step method. The two-step method is known in ophthalmic optics, but did not succeed in precision optics because of the lack of fast high precision grinding machines. Such a machine was built, using special spindles and numerical control. A computer controlled high precision centering and edging machine was built in order to enhance productivity and accuracy and to enable optical shops to produce even complicated lens shapes in an economical way.
