Description

1. Technical field

[0001] The invention belongs to a processing technology of optical elements, and is mainly used for the production of common optical glass and aspherical optical elements of silicon single crystal material. 2. Background technology

[0002] Through the search, no reports of the same or similar technology have been found. At present, the processing of optical glass and silicon single crystal material aspherical optical elements mainly adopts traditional polishing technology. The main process flow In general, only 2-order aspheric optical elements are processed, and high-order aspheric surfaces (more than 10 times) can barely be processed, but the produced elements have the defects of long cycle, high cost, and difficult to guarantee accuracy. 3. Content of the Invention

[0003] The main technical task and purpose of the present invention are: to find a new method according to the shortcomings of the traditional process for processing aspherical optical ...
