1. CNC single point diamond processing technology

At present, the materials that can be directly processed to meet the optical surface quality requirements using diamond turning technology are mainly non-ferrous metals, germanium, plastics, and infrared optical crystals. However, the processing of glass cannot meet the optical surface quality requirements and needs to continue to be polished and corrected. Another main application of CNC single-point diamond processing technology is to process various molds required for compression molding.

2. CNC grinding and polishing technology

The main processing material of CNC grinding and polishing technology is glass, which makes up for the lack of CNC single-point diamond processing technology that cannot directly process finished optical glass parts. This technology is mainly used for processing spherical and aspherical optical parts. It is the main technology to replace the traditional classical optical glass processing method. It has the advantages of high precision and high processing efficiency. At present, the development of this technology in the market has a relatively long history, and mature equipment is more comprehensive. For example, Satisloh, Optotech and Schneider in Germany have launched different types of milling and polishing machine tools. my country has also carried out a lot of research on CNC technology.

Computer numerical control grinding and polishing technology has not only made great progress in numerical control equipment automation and machining accuracy, but the research on various polishing methods and principles has greatly promoted the development of optical aspheric surface processing technology.

3. Optical lens molding technology

At present, optical lens compression molding technology has been used to mass produce spherical and aspheric lenses. It can not only manufacture commonly used medium-diameter lenses, but also extend to 100 micron micro-lens arrays and 50 mm larger-diameter lenses. It can not only manufacture spherical and aspheric optical parts in military and civilian optical instruments, but also manufacture optical communications. The aspheric lens used in the fiber coupler.
