Summary of the 2025 China (Beijing) International Optical Instrument Exhibition

    The 2025 China (Beijing) International Optical Instrument Exhibition will be held grandly at the Beijing National Convention Center from June 30th to July 2nd. Under the direct participation and organization of numerous domestic and foreign industry associations as well as government regulatory departments, this exhibition continues to exert strong influence in the field of optical instruments with its style of "clear theme, prominent features, emphasis on effectiveness, and continuous innovation". It has become the most authoritative, professional, and largest industry event in Asia, winning high praise from numerous exhibitors and visitors.

   Scope of exhibits and technical highlights: Optical components and materials: This exhibition area gathers a rich and diverse range of exhibits. In terms of optical glass, various glass materials with special optical properties, such as low dispersion glass, high refractive index glass, etc., have been demonstrated, which can be widely used in high-end optical lens manufacturing. Sapphire materials, quartz materials, and plastic lenses have also attracted a lot of attention, and lenses made of different materials have demonstrated extremely high levels of dimensional accuracy, optical uniformity, and other aspects. At the same time, related products such as grinding materials and coating materials are also readily available, providing a complete material solution for the production and processing of optical components. Various optical components such as filters, spectrometers, spherical and non spherical lenses, prisms, cylindrical mirrors, reflectors, flat windows, focusing mirrors, half mirrors, and beam expanders are dazzling. Some companies showcase non spherical lenses with surface precision reaching the nanometer level, representing the top manufacturing level in the current industry. Optical processing equipment: Various cold processing and non spherical processing equipment showcase the advanced technology of current optical processing. Single sided and double-sided grinding and polishing machines can achieve high-precision processing of lens surfaces through intelligent control systems, ensuring that the flatness, roughness, and other indicators of the lenses meet strict requirements. The emergence of molding equipment for spherical and non spherical lenses and electroplating equipment has improved the production efficiency of optical components and reduced production costs. Diamond turning equipment, with its high-precision machining capability, can perform precise turning on various optical materials and produce complex optical surfaces. Glass cutting machines, cutting machines, external circular saws and other equipment play an important role in the cutting and processing of optical materials, and their cutting accuracy and efficiency have been significantly improved. The crystal growth equipment showcases the preparation process from basic materials to optical crystals. Some companies have demonstrated new crystal growth technologies that can grow larger and higher quality optical crystals, providing high-quality raw materials for the manufacturing of optical components.

   This exhibition comprehensively showcased the latest development achievements and trends in the optical instrument industry, providing a platform for communication and cooperation between upstream and downstream enterprises in the industry, and promoting the coordinated development of the industry chain. At the same time, the exploration of industry development issues and the consensus reached during the exhibition will help guide industry enterprises to better respond to challenges, seize opportunities, and promote the development of the optical instrument industry towards higher levels and more innovative directions in the future. It will make positive contributions to the overall upgrading of China's optical industry and the enhancement of its international competitiveness.
