Compared with traditional lenses, Fresnel optical lenses have the advantages of large area, light weight, low price, and easy portability. They are widely used optical components, and their design and manufacturing involve multiple technical fields. Including optical engineering, polymer materials engineering, CNC machining, diamond turning process, nickel plating process; molding, injection molding, casting and other manufacturing processes. Therefore, the design, development, and production of large-scale, high-precision Fresnel lenses have become the main direction of technological development in the production departments at home and abroad.
