At present, multispectral/cleartran and standard CVD ZnS optics lens molding technology has been used to mass produce precision spherical and aspherical lenses. In general, in addition to the general production of lenses having a diameter of about 15 mm, it is also possible to produce large-diameter lenses, microlens arrays, and the like having a diameter of 50 mm. It is now possible to manufacture a microlens array of 100 μm in diameter per lens. (1) Manufacture of spherical and aspheric optical components used in military and civilian optical instruments, such as high precision ZnS optics lenses, prisms, and filters; (2) manufacturing an aspherical lens for a fiber coupler for optical communication; (3) A concentrating aspherical lens for manufacturing an optical disk. An aspherical lens made by a compression molding method can replace the three spherical lenses used in the optical lens of the optical disc reader. Due to the high precision of the molded aspherical lens, it is possible to control and correct the axial aberration of the large numerical aperture, and also reduce the weight and cost of the original optical lens by 30 to 50%. (4) An aspherical lens that manufactures a camera viewfinder aspherical lens, a film projector, and a camera lens, and the like. Only Kodak in the United States needs to press millions of aspherical wholesale large size optical grade sapphire optics parts every year.
