Micro and nano manufacturing technologies such as MEMS processes, nanoimprint, screen printing, femtosecond laser etching, and photolithography are all based on “Optics” as the medium, showing the active role of micro and nano optics. These technologies combine cutting-edge achievements in photonics and nanotechnology, enabling the realization of new functions at the micro and nano scale.

Ultra-precision machining technology serves as the primary method for fabricating micro and nano optical components. In the future, this technology will develop towards high precision, high efficiency, large-scale production, miniaturization, intelligence, process integration, online processing and testing integration, and environmentally friendly practices. These developments will drive the emergence of novel micro-nano processing technologies, allowing for the application of micro-nano structures and devices with various functions. They will also contribute to the development of new micro-nano optical devices and systems.

We believe that the next 50 years will be an era of vigorous development for ultra-precision micro-nano optical technology! We are organizing the “Ultra Precision, Micro Nano Processing and Optical Testing Forum” on March 8, 2024. This forum will bring together renowned enterprises, experts, and scholars in the fields of micro-nano optics, precision optical machining, and optical inspection to lead discussions on cutting-edge technologies and explore topics such as nanoimprint, micro-nano direct writing lithography technology, gray high-light lithography, precision machining, optical inspection, etc.
