Optical Glass Balls

Optical Glass Balls

Glass balls are chemically inert, have low liquid absorption as well as obvious optical characteristics. This makes the ideal choice for use in certain check valves, flow meters, low speed bearings, liquid applicators and a variety of other applications. Sizes, tolerances and surface finishes can be customized to meet individual customer requirements.

Optical glass balls are used as lenses are for collimating the output of an optical fiber or laser diode or for laser diode to fiber coupling.
