Due to the late start of my country’s optical industry and the relatively backward technology, my country’s optical companies are still in the traditional optical glass production stage, and their product technology content is relatively low. Due to my country’s low cost of raw materials, manpower, and energy, my country’s The medium and low-end optical glass products of the company have a competitive advantage in the world, and it is the world's largest traditional optical glass production base. High-end products are still produced by several large companies in Japan, Germany, and the United Kingdom, such as HOYA and OHARA in Japan, SCHOTT in Germany, CONRING in the United States, and Pilkington in the United Kingdom. my country only produces small batches; In comparison, my country's current overall technical level is at a low level, and some products have reached international standards. There is still a certain gap with foreign countries in terms of production technology, product quality stability, and new product development. The details are as follows: 　　 There are three large-scale domestic optical glass production enterprises: Chengdu Guangming Optoelectronic Information Materials Co., Ltd. (208 Factory); Shanghai Xinhu Glass Factory; Hubei Xinhuaguang Information Materials Co., Ltd. The production and sales of the above three companies have accounted for more than 80% of the domestic market. Chengdu Guangming Optoelectronic Information Materials Co., Ltd. is a leading enterprise in the same industry in China. In recent years, through technology introduction and marketing innovation, it has developed rapidly and its scale has grown rapidly. It has become a major optical material export enterprise in China.　　 The optical industry started to develop from downstream optoelectronic machines, driving the midstream optical component manufacturing and processing industry, and then driving the development of the upstream optical glass industry. In recent years, the development of the optoelectronic information industry has undergone major changes and presents the following characteristics: 　　 1. The traditional optical glass production base has shifted to the country, and the market fluctuates greatly. Before the 1960s, the development and production of optical glass Mainly in Europe and the United States, the products are mainly used in telescopes, gunsights, low-end cameras and optical devices of general optical instruments. From the 1960s to the 1970s, Japan first realized the continuous melting furnace in the production of optical glass, which triggered the structural adjustment of the world optical industry. The optical industry began to shift from the west to the east, making Japan the fastest growing optical industry in the world. country. In the late 1980s, with the gradual maturity of my country’s continuous melting production technology and the substantial reduction in manufacturing costs after the implementation of the market economy system, the production of traditional optical glass gradually shifted to China. Many optoelectronic companies in Japan and Taiwan have almost All camera companies and optical cold processing companies have set up factories in China, which has enabled my country's optical glass manufacturing industry to develop rapidly and shorten the gap with the world's advanced level. 2. Special quality and special optical glass are growing rapidly, and the market prospect is broad. Before the 1990s, the main markets for optical glass products were telescopes, microscopes, gunsights, low- and mid-range cameras, measuring instruments, analyzers and other traditional optical equipment. After the 1990s, with the rise of the information industry, optics and electronics are more closely integrated, and optoelectronic products are closely related to optical glass in the collection, transmission, storage, and conversion of information. The information industry has promoted the development of the optoelectronic industry. The emerging optoelectronic products have expanded the application range of optical glass. As digital information products have gradually become the main application areas of optical glass, the variety and product quality of optical glass materials have also changed. Special quality and special optical glass have high technical content and great added value. Its sales price can reach dozens of times that of traditional optical glass. It is the main profit growth point of the optical glass industry. It has become the mainstream product of the optical glass industry and will become The future development direction of this industry. Due to technical reasons, the supply of optical glass in this part of the market is mostly monopolized by foreign optical companies. Domestic companies have a small share of this market, and the market prospects are broad. 3. The industry is highly concentrated, and the industry has been upgraded. At present, special quality and special optical glass are mainly concentrated in Japanese HOYA, OHARA, German SCHOTT, American CONRING and other companies. They have successfully entered the optoelectronics industry with their advanced technology in the optical glass The industrial and information industry has become a high-tech enterprise integrating the production of special quality and special optical glass, optical components and optoelectronic products, and has successfully achieved product structure adjustment and industrial upgrading.　　 Because domestic companies have a certain gap with international advanced companies in terms of high-end products such as special quality and special optical glass, large foreign optical companies such as Japan's HOYA, OHARA, HIKARA, and Germany's SCHOTT have participated in my country's market competition. In order to serve the Japanese and Taiwan-owned optical processing enterprises transferred to mainland China, Japan's HOYA company has established a factory in Suzhou. German SCHOTT and Taiwan’s largest compact enterprise Lianyi will cooperate to produce glass blanks in China, and OHARA has been in 2003. Established a profiling factory in Zhongshan, Guangdong, with a production capacity of 10 million pieces/month.
