Sapphire material has good light transmission performance. Therefore, lens products made of sapphire material have a longer service life and a wide range of adaptive spectra. Compared with optical glass, they have obvious advantages. Process different types of sapphire lenses according to user needs, such as spherical lenses, cylindrical lenses, and prism series
