Problems solved by technology

[0004] Under normal circumstances, only 2 aspheric optical elements are processed. For high-order aspheric surfaces (more than 10 times), it is barely possible to process, but the manufactured elements have long cycle times, high costs, and difficult to guarantee accuracy. defect

Description

1. Technical field [0001] The invention belongs to a processing technology of optical elements, and is mainly used for making infrared optical materials—zinc selenide and zinc sulfide aspheric optical elements. 2. Background technology [0002] Through the search, no technical reports identical or similar to this one were found. At present, the processing of zinc selenide and zinc sulfide aspheric optical elements mainly adopts traditional polishing technology, and the main process flow is as follows: [0003] [0004] Under normal circumstances, only two aspheric optical elements are processed, and for high-order aspheric surfaces (more than 10 times), it is barely possible to process, but the components produced have long cycle times, high costs, and difficult to guarantee accuracy. defect. [0005] The main technical task of the present invention is: to find a new method to process zinc selenide and zinc sulfide aspheric optical elements according to the deficiency ...
