Global optical cold processing industry structure

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

The main processes of optical cold processing include pressing, cutting, milling, grinding, polishing, edging, bonding, and coating. Downstream products of 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 is mainly used to process optical lenses for its downstream products. There are two major categories of glass and plastic materials. Glass lenses are classified into two types: plane mirrors and lenses. Flat mirrors include flat glass and prisms. Lenses include spherical and aspherical mirrors. At present, the processing of aspherical mirrors by domestic companies 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 held by Japanese, American and German manufacturers, of which Japan has mastered the major sources of global optical cold processing technology. With the development of modern optoelectronic technologies in the past 10 years, optical technology developed countries have adjusted their own industrial structure and industrial development direction, gradually withdraw from the traditional optical processing field, and concentrate on the manufacturing and R&D of modern and high-end optoelectronic products; Taiwan, China It gradually became the center of optical cold processing in the world.

Germany: With a strong foundation in the optical industry, it has a high level of precision and high precision in optical cold processing. Zeiss lenses and laser cameras represent the highest level of traditional optical processing and camera manufacturing technology in the world. In recent years, Germany has used its advantages of high specialization and flexible production technology to develop modern optoelectronic technologies such as integrated optics, fiber optics, holography and laser technology. The lens manufacturing and lens design services in traditional optical processing have been mostly Outsourcing, relying solely 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 also basically shrunk. Instead, it is relying on its advantages in science and technology and capital to vigorously develop technology-intensive modern optoelectronic devices and instruments, such as: Processing equipment and detection instruments, intelligent spectroscopic 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 to speed up the transformation and product renewal of the traditional optical instrument industry, especially strengthen the original technology development and promote the change of the optical instrument industry. In terms of optical cold processing, except for a few high-precision lens and lens processing, Japan has basically withdrawn from the traditional optical cold processing industry, focusing on the development of optical design, optical detection equipment and detection technology, optical processing and coating equipment, etc. The manufacturing industry ranks the world's leading position and has become a major optical cold processing design, process, inspection technology and equipment exporter.

Taiwan, China: Taiwan is not a traditional optical technology developed region. However, with the adjustment process of the optoelectronic industry in developed countries, the Taiwan region has actively cooperated with international companies by virtue of its geographical and trade advantages, and gradually mastered sophisticated optical processing technologies, becoming a developed country in Japan and other developed countries. After quitting the field of optical cold processing, major technology and market undertakers have provided optical components for Japan and the United States, and have gradually cultivated the world's largest optical cold processing enterprise cluster represented by Yaguang, Dali, and Nowland. .

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 trend of international optoelectronic industry structural adjustment and industrial transfer, optical cold processing capacity in the world has been transferred to China on a large scale. Traditional optical processing companies in China have also seized the opportunity to transform themselves into modern optical processing companies. Through active cooperation with internationally advanced companies, domestic companies have rapidly expanded their production scale with manufacturing cost advantages, and have also achieved certain success in the research and development of precision optical technologies. The technology development of domestic companies is mainly from Japan, and the management experience of production process mainly comes from Taiwanese companies.

The main trend of the industrial restructuring of the optical cold processing industry is that the developed countries have basically withdrawn from cold processing and concentrated in the fields of modern optoelectronics and optical design; China has become the world’s largest optical cold processing capacity and the gathering ground.
