The optical cold processing industry mainly produces optical components, providing optical components such as lenses and lenses for downstream industries such as optical instruments and optoelectronic image information processing products, and is in the middle of the production of semi-finished products in the entire industrial chain.
The main processes of optical cold working are pressing, cutting, milling, fine grinding, polishing, edging, bonding, 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 optoelectronic 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. Flat mirrors include flat glass and prisms, and lenses include spherical mirrors and aspherical mirrors. At present, the processing of aspherical mirrors in 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, of which Japan has mastered the main source of the 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 own industrial structure and industrial development direction, gradually withdrawing from the traditional optical processing field, and concentrating on the manufacture and research and development of modern and high-end optoelectronic products; Taiwan, mainland China It has gradually become the manufacturing center of optical cold processing in the world.
Germany: With a solid optical industry foundation, high-level and high-precision advantages in optical cold processing, Zeiss lenses and Laika cameras represent the highest level of traditional optical processing and camera manufacturing technology in the world. 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 have been largely Outsourcing, relying only on brand management.
The United States has completely withdrawn from the optical cold processing industry with high labor costs and backward technology, and its traditional optical instrument industry has basically shrunk. Instead, relying on technology and capital advantages, it vigorously develops technology-intensive modern optoelectronic equipment and instruments, such as: micro Processing equipment and testing instruments, intelligent spectral 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 renewal 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 field of optical design, and has developed in optical testing equipment and testing technology, optical processing and coating equipment, etc. In terms of manufacturing, it takes the leading position in the world and has become the main exporter of optical cold working design, process, testing technology and equipment.
Taiwan, China: Taiwan is not an area with developed traditional optical technology, but along with the process of structural adjustment of optoelectronic industries in developed countries, Taiwan, relying on its geographical and trade advantages, actively cooperates with international companies, gradually masters sophisticated optical processing technology, and has become a developed country such as Japan. After withdrawing from the field of optical cold processing, the main technology and market undertakers have provided a large number of optical components for Japanese and American companies, and have gradually cultivated the world's largest optical cold processing enterprise cluster represented by Yaguang, Dali, Jingu, etc. .
China: Compared with developed countries, China's optical cold processing technology level is relatively low, and 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 trend of international optoelectronic industry structure adjustment and industrial transfer, the optical cold processing capacity worldwide has been transferred to China on a large scale, and domestic traditional optical processing enterprises 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 mainly comes from Taiwan enterprises.
The main trend of industrial structure adjustment in the optical cold processing industry is: developed countries have basically withdrawn from cold processing and concentrated in the field of modern optoelectronic technology and optical design; China has become the world's largest optical cold processing capacity undertaking and gathering place.
