The industries closely related to the precision optical device industry are the visual material production industry and the optical instrument industry. Among them, the optical material production industry is upstream of the precision optical device industry, and the optical instrument industry is downstream of the precision optical device industry.
In recent years, global precision optics has developed rapidly. It has been widely used in aerospace, life science and medical treatment, semiconductor lithography and testing equipment, unmanned, biometric, AR, VR testing equipment, military, scientific research, and other fields. With the rapid development of the above market areas, the demand for precision optical products has further increased, providing a good market prospect for developing the world precision optics industry.
With the rapid promotion of the popularity of traditional 3C consumer electronics products such as smartphones, tablets, and digital cameras, its market has gradually matured and formed a relatively stable competition pattern. Under the context of aerospace development, life science, and medical treatment, semiconductor lithography and detection equipment, unmanned driving, biometrics, AR/VR detection equipment, new challenges have been posted to the limitation of optical systems. Thus it's required to promote the application field from consumer-level to industrial level.
In the scientific community, the manufacturing technology of precision optical components is moving towards the limit of human manufacturing capacity. Countries worldwide develop science and technology, show national strength and boost the development of advanced manufacturing, space exploration, aerospace, and other fields by implementing various large-scale optical projects. For example, in the field of deep space exploration, the large aperture optical devices used by aircraft should meet the requirements of lightweight and ultra-precision while realizing super large size (more than 1.5m), including λ/10 surface accuracy and nanoscale surface roughness. The materials involved include fused quartz, zero expansion glass, and silicon carbide, and so on. In the semiconductor field, to meet the requirements of integrated circuit manufacturing technology development, extreme ultraviolet lithography is becoming the core technology developed by many countries in the world. The requirements for the surface accuracy of optical devices meet the requirements λ/ 200, the surface roughness is less than 0.1nm, and these two indexes reach or even exceed the limit of current optical manufacturing technology.
The improvement of industrial precision optics design ability and manufacturing technology is the inevitable requirement of the development of science and technology and an important basis for the development and progress of science and technology.
