Asphere Lenses

Molded glass aspherical 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 glass aspherical lenses with high-precision contour accuracy and surface quality. . The advantages of the lens are low production cost, high precision, and suitable for mass production.
