Global Optical Cold Processing Industry Structure

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

The main processes of optical cold working are profiling, cutting, milling, fine grinding, polishing, edging, bonding, coating, etc. The final products of the downstream industry include digital cameras, camera phones, scanners, projectors, rear projection TVs, DVD players, bar code readers and other optical instruments and optoelectronic digital products. Optical cold processing mainly for its downstream products processing optical lenses, from the material to distinguish, there are two categories of glass and plastic. Glass lenses are divided into two categories: plane mirrors and lenses, in which plane mirrors include flat glass and prisms, and lenses include spherical and non-spherical mirrors. At present, the processing of non-spherical 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 global optical cold processing technology. With the great development of modern optoelectronic technology in the past 10 years, the developed countries of 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 and mainland China have gradually become the manufacturing centers of optical cold processing in the world.

Germany: With a strong optical industrial base and high-level and high-precision advantages in optical cold processing, Zeiss lens and Laika camera represent the highest level of traditional optical processing and camera manufacturing technology in the world. In recent years, Germany has made great efforts to develop modern optoelectronic technology, such as integrated optics, fiber optics, holography and laser technology, taking advantage of its high degree of specialization and flexible production technology. Most of the lens manufacturing and lens design business in traditional optical processing has been outsourced and only relies on brand management.

The United States: It 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, it relies on the advantages of science and technology and capital to vigorously develop 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 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 amount 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 field, and has taken a leading position in the world in the manufacture of optical testing equipment and testing technology, optical processing and coating equipment, and has become a major exporter of optical cold processing design, process, testing technology and equipment.

Taiwan, China: Taiwan is not a region with developed traditional optical technology, but with the process of structural adjustment of optoelectronic industry in developed countries, Taiwan, relying on its geographical and trade advantages, actively cooperates with international enterprises and gradually masters sophisticated optical processing technology, becoming the main technology and market acceptor after Japan and other developed countries withdraw from the field of optical cold processing, providing a large number of optical components for Japanese and American enterprises, it 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 level is 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 trend of structural adjustment and industrial transfer of the international optoelectronic industry, the worldwide optical cold processing capacity 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 the industrial structure adjustment of 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 to undertake and gather.
