In-depth analysis of precision optical components technology and prospects: With the rapid development of modern optoelectronic products and the acceleration of upgrading, products are becoming more and more miniaturized, digital and functionally integrated, the demand for precision optical components is increasing, and the requirements for product precision and optical indicators are also constantly improving, which puts forward higher requirements for the processing and testing capabilities of precision optical components. In the face of increasing requirements, the precision optics industry has made great progress in technology by introducing and absorbing advanced technologies in other fields

(1) Advanced manufacturing and testing technology is continuously integrated into the precision optical processing industry: With the improvement of the accuracy of precision optical components and the development of large-scale production, advanced manufacturing and testing technology are continuously integrated into the precision optical processing industry. At present, numerical control machining technology (CNC), computer-aided design (CAD), ion beam-assisted processing technology, high-speed fine grinding, high-speed polishing, laser centering and other technologies have gradually begun to be applied to the processing process of optical components on a large scale, and are gradually replacing the traditional processing technologies such as classical polishing that have been applied for decades. Laser plane interferometer and other automatic detection instruments began to be widely used in the processing of optical components, through computer and software analysis technology non-contact automatic judgment of surface shape and processing accuracy, is replacing the traditional optical sample contact inspection and the need for personal subjective judgment of surface shape and processing accuracy of the detection method. The integration of advanced manufacturing and testing technology not only greatly improves production efficiency and quality assurance capabilities, but also changes the situation that optical processing technology relies on individual operation skills and experience, providing a reliable guarantee for the large-scale production of precision optical processing industry.

(2) Optical thin film technology has become a key technology to promote the development of the precision optical processing industry: the spectroscopic characteristics of optical components can only be achieved by relying on the polarization and spectroscopy, anti-reflection, and accurate positioning of spectral wavelengths of optical thin films. Precision optical components have higher and higher requirements for the spectral control ability and accuracy of optical thin films, and the design of optical films is becoming more and more complex, and the number of film layers of optical thin films requiring high performance has reached more than 100 layers, and there are ultra-thin layers with a thickness of only a few nanometers. Stable coating processes and monitoring technologies are key factors in ensuring high-quality optical films. Due to the high technical threshold, the current efficient, high-quality, low-cost mass production technology is still only mastered by a few optical processing enterprises. The precision coating technology, which was mainly used in the manufacture of integrated circuits, represented by sputtering film deposition technology and plasma chemical vapor deposition film forming technology, has been gradually used in optical coating, and the film thickness detection method has been continuously optimized and improved, which has improved the coating efficiency and product yield and reduced the cost significantly, and has become a key technology to promote the development of the precision optical processing industry.
