METHOD AND DEVICE FOR THE PRODUCTION OF PRECISION LENSES

摘要

The invention relates to a device (1) and a method for producing an optical lens, especially a precision lens (60, 61, 62). According to the invention, a curvature (50) is pressed into an essentially planar surface (41) of a glass blank (40), particularly a glass bar, by means of a first compression mold (45) without the first compression mold (45) touching the surface (50A) of the curvature (50) or a substantial portion of the curvature (50) while the curvature (50) is pressed into a second compression mold (45), said second compression mold (45) touching a substantial portion of the curvature (50).
