Optical Ball Lenses for Fiber Optic applications | |
 |
The Ball Lenses shown have diameters of 0.30, 0.50, 0.80, 1.00, and 3.0 mm (about 0.012 to 0.12 inch) Anti-Reflection Coating is available. SJC Ball Lenses range in diameter from 0.25 to 5.0mm and have perfect spherical roundness with excellent surface quality. Our standard precision is ± 2.5μ on the basic diameter with a Sphericity of 0.25μ equal to Grade 10. Tighter tolerances can be quoted upon request. SJC's Optical Ball Lenses are available in a variety of sizes and glass types or sapphire according to the Index of Refraction desired.

Ball lenses are used for light coupling in fiber-optic applications. The choice of the optical ball lens depends on various parameters such as the diameter of the laser beam, the numerical aperture of the fiber and the wavelength of the light. |
