Ball Lens, Spheres, Half glass sphere


Spherical ball lenses are commonly used for laser collimating and focusing, laser-to-fiber coupling, fiber-to-fiber coupling, and fiber-to-detector coupling. We make this spherical ball lenses from all kinds of optical glass material.

We manufacture Ball Lenses from Low Melting Point Glasses, which are specially developed for PGM (Precision Glass Molding). The low Melting Point Ball lenses extend the life of the mold and reduce the reaction between the glass and the mold. This low melting point Ball lenses are used for spherical or aspheric lenses precision molding.


Material: Optical glass: for example, K9, BK7, B270, SF11, Fused silica, etc.
              Low Melting Point Glass: for examples, CDGM's D-K9(516641), D-K59(518635),
              D-ZK3(589612); Coring CO550(605504), etc.
