Overview of the development of the precision optical components industry

With the progress of science and the development of the industry, precision optical components have been widely used in life, and the future development trend is upward as a whole.

Introduction to Precision Optical ComponentsOptical components refer to the main devices in optical systems that use optical principles for various observations, measurements, analysis and recording, information processing, image quality evaluation, energy transmission and conversion, etc. As the basic optical products that can undertake the transmission, control and carrying of technical information of light, optical components are an important part of the core components of various optical instruments, image display products and optical storage devices.

Optical components can be classified differently according to different standards, among which optical components are divided into traditional optical components and precision optical components according to accuracy and use. Traditional optical components are mainly used in traditional optical products such as traditional cameras, telescopes, and microscopes; Precision optical components are mainly used in telescopes, microscopes, cameras, video cameras, copiers, optical instruments, equipment, as well as various wide-angle lenses, long focal lengths, zoom lenses and various filter lenses. In the manufacturing process of precision optical components, computer technology, CNC machining technology, automatic control and precision multi-layer coating technology, gluing technology and high-speed fine grinding, high-speed polishing and finishing, ultra-fine precision machining technology are combined, which significantly improves the accuracy and quality of optical components, and usually its accuracy requirements are increased by an order of magnitude compared with traditional optical components.

From the perspective of the layout of the industrial chain, the upstream industries related to the industry are mainly optical materials, the direct downstream of the industry mainly includes display devices and optoelectronic machines and other industries, and its terminal application markets mainly include televisions, computers, tablets and other display fields.

In the upstream of the industrial chain, optical materials are mainly optical glass and optical plastics, but due to the shortcomings of optical plastics, such as thermal expansion, easy water absorption, solvent resistance, poor wear resistance, and narrow optical coefficient range, optical glass is still an important optical material at present. Optical glass as a whole is in a state of supply and demand balance, and the price is steadily declining. In the downstream of the industrial chain, optoelectronic technology has been combined into the whole machine products, due to the optoelectronic technology derived from many optoelectronic products, directly facing consumers, the industry scale is huge, directly driving the development of the entire optoelectronic industry, thus also driving the growth of the optical components industry.
