Abstract (en)
[origin: EP1977860A1] The method involves providing blanks (20), and processing blanks with abrasive fluid jet (32) for carrying materials of blanks. The fluid jet exhibits a radiation diameter, which is larger than the dimension of the blanks in a plane perpendicular to the direction of the fluid jet. The fluid jet is aligned under two different incident angles on the blanks for processing of the blanks in such a manner that a desired stripping profile is reached. An abrasive material such as cerium oxide and silicon carbide, is attached to the fluid jet. Independent claims are also included for the following: (1) a device for manufacturing optical elements e.g. aspherical mini and micro lenses (2) a computer program product, in which a base cutting profile is stored.
