The optical cold processing industry mainly produces optical components and provides lenses, lenses and other optical components for downstream industries such as optical instruments and optoelectronic image information processing products. It is in the middle of the production of semi-finished products in the entire industrial chain.

The main processes of optical cold processing include profiling, cutting, milling, fine grinding, polishing, edging, joining, coating, etc. The final products downstream of the industry include digital cameras, camera phones, scanners, projectors, rear projection TVs, DVD players, barcode readers and other optical instruments and photoelectric digital products. Optical cold processing mainly processes optical lenses for its downstream products, which are divided into two categories: glass and plastic. Glass lenses are divided into two categories: flat mirrors and lenses. The flat mirrors include flat glass and prisms, and the lenses include spherical and aspherical mirrors. At present, the processing of aspheric mirrors by domestic enterprises is still in its infancy, and glass spherical mirrors are still the mainstream products.

The top technology of the global optical cold processing industry is mainly in the hands of Japanese, American and German manufacturers, and Japan has mastered the main source of global optical cold processing technology. With the great development of modern optoelectronic technology in the past 10 years, developed countries in optical technology have adjusted their industrial structure and industrial development direction, gradually withdrew from the traditional optical processing field, and concentrated on the manufacturing and R&D of modern and high-end optoelectronic products; Taiwan, China It has gradually become the manufacturing center of optical cold processing in the world.

Germany: It has a solid optical industry foundation and high-level and high-precision advantages in optical cold processing. Zeiss lenses and Leka cameras represent the world's highest level of traditional optical processing and camera manufacturing technology. In recent years, Germany has taken advantage of its high degree of specialization and flexible production technology to vigorously develop modern optoelectronic technologies, such as integrated optics, fiber optics, holography and laser technology, etc. The lens manufacturing and lens design business in traditional optical processing has been mostly Outsourcing depends only on brand management.

The United States: It has completely withdrawn from the optical cold processing industry with high labor costs and backward technology. Its traditional optical instrument industry has basically shrunk. Instead, relying on technology and capital advantages, it has vigorously developed technology-intensive modern optoelectronic equipment and instruments, such as micro Processing equipment and testing instruments, intelligent spectroscopy instruments, biochemical and medical instruments, optical remote sensing instruments, laser interferometers, printers and other optical and optoelectronic instruments.

Japan: Make full use of the advantages of electronic technology, accelerate the transformation and product update of the traditional optical instrument industry, especially strengthen the development of original technology, and promote the change of the optical instrument industry. In terms of optical cold processing, except for a small number of high-precision lenses and lens processing, Japan has basically withdrawn from the traditional optical cold processing industry, focusing on the development of optical design, and in optical inspection equipment and inspection technology, optical processing and coating equipment, etc. In terms of manufacturing, it is a world leader and has become a major exporter of optical cold processing design, technology, testing technology and equipment.

Taiwan, China: Taiwan is not an area with developed traditional optical technology, but with the adjustment process of the optoelectronic industry in developed countries, Taiwan has actively cooperated with international companies based on its geographical and trade advantages, and gradually mastered sophisticated optical processing technology, becoming a developed country such as Japan After exiting the optical cold processing field, the main technology and market undertaker has provided a large number of optical components for Japanese and American companies, and has gradually cultivated the world's largest optical cold processing enterprise cluster represented by Yaguang, Dali, and Jinguo. .

China: Compared with developed countries, China's optical cold processing technology is relatively low. The traditional cold processing industry is mainly limited to optical lens processing, production of telescopes, traditional cameras and other low-end traditional optical instruments. In recent years, under the restructuring of the international optoelectronic industry and the trend of industrial transfer, the world's optical cold processing capacity has been transferred to China on a large scale. Traditional optical processing enterprises in China have also seized the opportunity to transform into modern optical processing enterprises. Through active cooperation with international advanced enterprises, domestic enterprises have rapidly expanded their production scale by virtue of their manufacturing cost advantages, and have also achieved certain success in the research and development of precision optical technology. The technological development of domestic enterprises mainly comes from Japan, and the management experience of production process flows mainly from Taiwanese enterprises.

The main trend of the industrial structure adjustment of the optical cold processing industry is: developed countries have basically withdrawn from cold processing and concentrated in the fields of modern optoelectronic technology and optical design; China has become the world's largest optical cold processing capacity undertaking and gathering place.
