产品描述：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.

Foctek manufactures 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.
