Molded glass aspheric lenses use ultra-high-precision molds to perform high-temperature molding on glass glass materials under the protection of inert gas at set high temperatures and pressures to produce molded glass aspheric lenses with high-precision contour accuracy and surface quality. The advantages of the molded lenses are low production cost, high precision, and suitable for mass production.
