Optical cold-processing industry mainly produces optical components, optical instruments, optoelectronic image processing products such as the downstream industry to provide lenses, lenses and other optical components in the composition of the entire industrial chain in the middle of the production of semi-finished products.
Optical cold-processing of the main processes are pressure type, cutting, milling, grinding, polishing, edging, bonding, coating and so on. The downstream products in the 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 its downstream products mainly for the processing of optical lenses, from the material distinction, there are two major categories of glass and plastic. Glass lenses are divided into two categories of flat mirrors and lenses, including flat mirrors including flat glass and prism, the lens includes a spherical lens and aspherical mirror. At present domestic enterprises aspheric mirror processing is still in its infancy, glass ball mirror is still the mainstream products.
The most advanced technologies in the global optical cold-working industry are mainly in the hands of Japanese, U.S. and German manufacturers, of which Japan has mastered the major sources of global optical cold-processing technology. With the great development of modern optoelectronic technology in recent 10 years, the developed countries of optical technology have adjusted their own industrial structure and industrial development direction one by one, gradually withdrawing from the traditional optical processing field and concentrating on the manufacturing and R & D of modern and high-end optoelectronic products; and Taiwan and mainland China Then gradually become the world's optical cold manufacturing center.
Germany: With a strong optical industry base and high level of precision in optical cold processing, Zeiss lenses and Cameras represent the highest standard in the world of traditional optical processing and camera manufacturing. In recent years, Germany has made great efforts to develop modern optoelectronic technologies such as integrated optics, fiber optics, holography and laser technology by taking advantage of its high degree of specialization and flexibility in production technology. Most of the business of lens manufacturing and lens design in traditional optical processing Outsourcing, relying solely on brand management.
The United States: It has completely withdrawn from the labor-intensive and backward process of optical cold-working industry. Its traditional optical instrument industry has basically shrunk. Instead, it relies on technology and capital advantages to develop technology-intensive modern optoelectronic equipment and instruments such as: fine Processing equipment and testing equipment, intelligent spectroscopy equipment, biochemical and medical equipment, optical remote sensing instruments, laser interferometers, printers and other optical and optoelectronic devices.
Japan: Making full use of the advantages of electronic technology to speed up the transformation of traditional optical instruments industry and product updates, in particular, to strengthen the development of original technologies to promote the optical instrument industry changes. In the field of optical cold processing, Japan has basically withdrawn from the traditional optical cold-working industry with the exception of a few high-precision lenses and lens processing. The focus has been on the field of optical design. In the fields of optical inspection equipment and inspection technology, optical processing and coating equipment, etc. The leading manufacturer in the world, becoming the major optical cold-processing design, technology, testing technology and equipment exporter.
Taiwan: Taiwan is not a developed region with traditional optical technologies. However, with the structural adjustment of the optoelectronics industry in developed countries, Taiwan, by virtue of its geographical and trade advantages, is actively cooperating with international companies to gradually acquire sophisticated optical processing technologies and become a well-developed country such as Japan After exiting the field of optical cold processing, the major technology and market undertakers provided a large number of optical components to Japanese and American enterprises and gradually cultivated the world's largest optical cold-processing business cluster represented by Asia, Dali, .
China: Compared with developed countries, China has a relatively low level of optical cold processing technology. The traditional cold-working industry is mainly limited to middle and low-end traditional optical instruments such as optical lens processing, production of telescopes and traditional cameras. In recent years, with the adjustment of the international optoelectronics industry and the trend of industrial transfer, the worldwide capacity of optical cold-processing has been shifted to China on a large scale. The domestic traditional optical processing enterprises have seized the opportunity to transform themselves into modern optical processing enterprises. Through active cooperation with advanced international enterprises, domestic enterprises rely on manufacturing cost advantages to rapidly expand the production scale of their enterprises and have achieved some success in the research and development of sophisticated optical technologies. The technological development of domestic enterprises mainly comes from Japan, and the management experience of production process mainly comes from the Taiwanese enterprises.
The main trends in the industrial restructuring of the optical cold-working industry are: the developed countries have basically withdrawn from cold-working and are concentrated in the field of modern optoelectronic technology and optical design; and China has become the largest undertaking and gathering place for optical cold-working capacity in the world.
