On the afternoon of June 30, He Wenbo, chairman of China's leading high-precision optical lens manufacturer FJFG Optical Technology Group, talked about the current status and prospects of the optical lens industry, as well as the company's development opportunities and challenges.
He Wenbo said, "The company continues to stabilize and enhance its position in the aerospace, defense, security and other markets, while further expanding the application field of customized products, actively exploring new markets such as vehicle lenses, infrared lenses, and machine vision lenses, focusing on advancing the new generation of information technology. In-depth application and technical upgrades in various fields have become the world's leading professional optical system supplier, playing a substantial role in the technological breakthroughs and application promotion of the Internet of Things, artificial intelligence, and big data."
Chairman He Wenbo said that the company has established two pillars: special optical lenses and systems, civilian optical lenses and systems. "
At present, FJFG has developed into a high-tech enterprise specializing in the research and production of special and civilian optical lenses, optoelectronic systems, optical components and other products. It is an important manufacturer of optical lenses in the world and has been listed on the Hong Kong Stock Exchange in July 2019. Go public.
The special optical lens and photoelectric system developed by FJFG are widely used in China's aerospace projects such as: "Shenzhou series", "Chang'e lunar exploration", "Mars exploration" and other major national aerospace missions, as well as information and intelligent high-end equipment, The core clients include scientific research institutes and enterprises under the Chinese Academy of Sciences and major military industrial groups.
In addition, FJFG has integrated special product technology into the field of civilian products. Since 2005, it officially launched the first civilian product security monitoring zoom lens, which has promoted the domestic substitution process of imported lenses from Japan and South Korea in the field of domestic security monitoring. The company has replaced the Japanese-led all-in-one machine technical solution with the zoom lens technology with independent intellectual property rights. A series of zoom lenses have been developed to replace Japanese products one after another, ensuring the independence and controllability of Chinese security products.
With the development and application of technologies such as the Internet of Things and artificial intelligence, human society has gradually transitioned from the traditional information society to an intelligent society. As the front-end photoelectric sensing core device of the new generation information system, the optical lens has become the "eye" of the information world. With the promotion of the new generation of information technology, it has been deeply applied to various fields of society to become an infrastructure. In this context, the future development prospects of optical lenses are crucial.
He Wenbo said to reporters that the military field is developing from mechanization and informatization to intelligence, and the military application of artificial intelligence is becoming a hot field of research at home and abroad. Intelligent weapons integrate photoelectric sensing, high-speed processing, and artificial intelligence into one, with memory, analysis, and comprehensive capabilities. Among them, the photoelectric system is in the front-end perception link, which will benefit from the intelligent trend of weaponry and be more widely used.
In the civilian field, He Wenbo said, "Civil optical lenses continue to develop in the direction of high resolution, large magnification, ultra-wide angle, miniaturization, large aperture (smaller F value), etc., further expanding the downstream market space. Camera technologies such as high-definition, The development of low illuminance, etc. has enabled the Internet of Things and artificial intelligence systems to collect higher quality information and data, improving the efficiency and accuracy of the system."
Four core technologies lead the development
"The company has four core technologies, namely the design and manufacturing technology of large-aperture transmission astronomical observation lens, the design technology of complex zoom optical system, the development and production technology of multi-spectral common-aperture lens and the design and miniaturization of fixed zoom aspheric lens and Automated production technology. Among them, the design and manufacturing technology of the large-diameter transmission astronomical observation lens is at the international advanced level, mainly used in the company's aerospace engineering series of lenses; the other three technologies also have certain leading advantages in China." He Wenbo introduced .
Aiming at the top optical in Europe
The optical lens industry has experienced more than 100 years of development since its birth. The early optical lens industry was mainly concentrated in Germany, represented by Carl Zeiss and Leica. Zeiss lenses are still typical representatives of the world's lens manufacturing technology.
According to reports, the design of optical lenses is very complicated. The design process requires years of experience and imagination. The demand and goal of optical technology is to transcend human eyes and provide human beings with visual information beyond time and space limitations. The optical design is to eliminate the difference between the imaging and the actual image in order to meet the requirements for distance, angle, and sharpness in different use scenarios, and obtain a perfect imaging effect.
He Wenbo said: "It is impossible to achieve a perfect imaging effect, and we can only achieve a balance among many requirements through optical design. Therefore, there is no perfect lens in this world, and the optical lens industry will never end in progress."
In March 2019, the Ministry of Industry and Information Technology and other three departments jointly issued the "Ultra HD Video Industry Development Action Plan (2019-2022)", which pointed out that in accordance with the overall technical route of "4K first, 8K", vigorously promote ultra High-definition video industry development and applications in related fields. In 2022, the overall size of my country's ultra-high-definition video industry will exceed 4 trillion yuan, the number of ultra-high-definition video users will reach 200 million, the 4K industry ecosystem will be basically improved, and breakthroughs will be made in the research and development and industrialization of 8K key technology products.
The future development of optical lenses is still very large, especially in the field of security. According to the TSR2018 edition of the "Marketing Analysis of Lens Units Markets" survey report, it is expected that in the next few years, global optical lenses will continue to grow to 2022. Among them, the global security video surveillance lens market will also maintain steady growth. In 2018, the global market sales were 252 million, an increase of 35.6% year-on-year in 2017. It is expected that the global market sales will reach 330 million in 2022, with an average growth rate of 8 in the next 4 years %/year.
"At present, China has achieved the application and industrialization of multiple technologies such as high resolution, aspherical surface, freeform surface, etc. But there is still a gap with Europe's top optics, such as ASML (Asm) lithography lens, which cannot be produced in China. "He Wenbo said that our company's benchmark for the next ten years is Europe's top optics, and one of the "super-precision processing" in the fundraising project is also preparing and improving.
