Optical Glass Lenses are manufactured from high-quality materials such as BK7, fused silica, and optical-grade crown or flint glass. These lenses are produced through precision melting, molding, grinding, polishing, centering, and coating processes. Optical design includes spherical, aspheric, and plano-convex geometries to control focal length, aberration, and beam propagation. They are widely used in imaging systems, laser modules, microscopes, and industrial inspection equipment. Optical performance depends on surface accuracy, material homogeneity, and coating quality.
