Sapphire Ball Lens & Hemispherical Lens |
|
Sapphire is ideal material for ball lens because of its excellent transmission bandwidths between the UV and IR at 0.15-5.5µm and high refractive index of 1.75. Ball lens out of sapphire exhibits exceptional performance like mechanical, optical, thermal and chemical robustness. |
Sapphire ball can be made with drilled holes, ground into hemispherical lenses and drum ball lenses. Sapphire ball can be antireflection (AR) coated to minimize reflection for optical applications. |
Typical applications of precision sapphire ball include fiber communication, flow meters, rotameters, bar code readers, check valves and laser measurements systems. |
