Optical glass refers to glass that can change the direction of light propagation and can change the relative spectral distribution of ultraviolet, visible or infrared light. Optical glass can be used to manufacture lenses, prisms, mirrors and windows in optical instruments, and is a key component of optical instruments. With the rapid development of global cameras, smart phones, security surveillance, vehicle lens, AR/VR, drones and other industries, the downstream demand for optical glass continues to grow. According to the '2019-2023 China Optical Glass Industry Market Monitoring and Future Development Prospects Research Report' released by the New Thinking Industry Research Center, the global optical glass industry is mainly concentrated in Japan, South Korea, Mainland China and Taiwan, in order to reduce costs , To improve competitiveness, and the global optical glass industry is gradually shifting to mainland China, which makes the scale of my country's optical glass industry expand rapidly. In 2018, the size of my country’s optical glass market was approximately 3.1 billion yuan, accounting for more than 60% of the total global scale. The world’s top two manufacturers, Chengdu Guangming Optoelectronics and Hubei Xinhuaguang, are both Chinese companies, and my country has become The world's main production area for optical glass.　　 In the downstream application market of optical glass, the share of traditional optical industries such as digital cameras and video cameras has continued to shrink. The smartphone market has become increasingly saturated and demand growth has slowed down. However, the demand for optical glass in these three areas, especially the smartphone sector, is still huge. The development of emerging industries such as security surveillance, vehicle cameras, AV/VR, sports DV, drones, and home projectors has accelerated, becoming a new driving force for the growth of the optical glass market. In general, the development prospects of the optical glass industry are broad. The scale of my country's optical glass industry continues to expand, but compared with Japan, Chinese companies still have a certain gap in technology, process, and equipment. Except for a few companies, most companies are generally small in scale, and their products are mainly concentrated in the middle and low-end areas. , The development situation of oversupply appears. In the high-end sector, the technical level is insufficient, and the market is dominated by imported products. The overall competitiveness of my country's optical glass industry is relatively low. With the acceleration of digital cameras and smartphone update iterations, and the continuous advancement of emerging industry technologies such as AR/VR, sports DV, and drones, the market has continuously improved the quality, performance, stability, and integration requirements of optical instruments. The technical content of optical glass is continuously rising. Increasing Ru0026D and innovation and developing into high-precision fields have become an important trend in the optical glass industry. This will drive the industry's technical thresholds to become higher and higher, and it will become increasingly difficult for small and medium-sized optical glass companies to survive.　　 New thinking circles industry analysts said that my country is a global optical glass production country, but the overall competitiveness of the industry is not strong, and the high-end market is mainly monopolized by imported products. With the continuous advancement of technology in the downstream industry and the acceleration of product update iterations, the market has continuously improved the quality and performance of optical glass. The development of the high-end field has become an inevitable trend for my country's optical glass industry. Under this circumstance, the market will further move closer to leading companies, and the strength gap between other companies and leading companies will become larger and smaller, small and medium-sized enterprises will gradually be eliminated, and industry concentration will continue to increase.
