With the progress of science and technology, ultra-precision machining technology has entered a new era of nano-manufacturing. In this cutting-edge field, the high standard requirements of nanoscale manufacturing technology for technical strength and resources have become the focus of international competition. The United States, Japan and many European countries, as well as China, have invested a lot of research power in this field. They focus on cutting-edge technologies such as electron beam exposure and atomic force microscopy nanofabrication, which operate at the molecular and atomic levels to achieve precise machining of nanoscale patterns and structures in electronic materials such as silicon and gallium arsenide, as well as a variety of non-metallic and metallic materials.

In order to further promote the rapid development of precision optics itself and its industrial integration in the application field, key breakthroughs in the development of the industry are achieved. On April 22-23, 2025, "2025 China (Chengdu) International Precision Optical Technology Application Conference" will join hands with Tongji University and Hong Kong Applied Science and Technology Research Institute, inviting well-known enterprises and research institutes/universities in the industrial chain. Starting from optical superlens, micro and nano manufacturing, freeform surface design, ultra-precision machining, CD-SEM measurement, semiconductor defect detection, and the renewal and application of optical films, the four topics of Micro and Nano Optics Frontier Technology, Ultra-Precision Micro and Nano Processing and Manufacturing, Semiconductor Measurement, and Optical Film High-Precision Production Technology are comprehensively and deeply discussed, and a large optical industry chain platform is built.
