Ball & Half Ball Lenses

 

This product is polished hemispherical lens made of optical glass fused silica, sapphire, or other optical materials which have a relatively high transmission rate for a diode with an anti-reflection coating. Widely used for coupling light in and out of fibers. It has the advantage of being easy to fabrication and light weight which can be considered the ideal component for optical communication applications.

 

Although due to the spherical aberration which leads to lower coupling efficiency, its unique easy-packaging attribute guarantees ball lenses are suitable for series production for optical communication applications with no doubts, especially compared to aspheric lenses.
