An aspheric mirror is an optical element with a non-spherical curved surface, which can be used to change the direction of propagation and focusing performance of light. Compared with the traditional spherical mirror, the non spherical mirror has higher focusing ability and smaller aberration, so it is widely used in the optical system.

The processing and production of the non-spherical mirror is a complex process, which requires high-precision processing equipment and precise processing technology.

First, the manufacture of an non-spherical mirror requires the determination of the desired surface shape and parameters. This usually requires optical design and simulation analysis to determine the shape and parameters of the surface. Then, according to the design requirements, select the appropriate material, and pre-processing.

Next is the processing of non spherical mirror. There are many methods for processing the non-spherical mirror, such as mechanical processing, optical processing and electrolytic processing. Among them, machining is one of the most commonly used methods. The main steps of machining include: making molds, using CNC machine tools for CNC machining, precision grinding and polishing, etc. These steps require high-precision processing equipment and skilled operators.

In the process of processing, strict quality control is also required. This includes indicators that control machining errors, surface roughness, and optical properties. Commonly used quality control methods include real-time inspection using precision measurement tools and comprehensive optical performance testing using optical test instruments.

Finally, the completed processing of the non spherical mirror also need to go through the surface treatment and coating and other links. The surface treatment can improve the optical performance and wear resistance of the non spherical mirror, while the coating can enhance the reflection and transmission of the non spherical mirror.

In a word, the processing and production of the non spherical mirror is a complex and precise process.
