>> Product Description Spherical Ball
Lenses are commonly used for laser collimating and focusing,
laser-to-fiber coupling, fiber-to-fiber coupling, and
fiber-to-detector coupling. Larger spheres are easier to handle and
ease the sensitivity of translational alignment. However, smaller
spheres has the benefit of fitting into smaller packages.Ball
lenses are highly polished spheres made of optically transparent
homogeneous materials. Carefully controlled manufacturing process
produces spheres withprecise diameters and unsurpassed surface
quality. We supply optical spherical ball
lens,Half-ball (hemispherical) lenses are ideal for applications
such as fiber communication, endoscopy, microscopy, optical pick-up
devices, and laser measurement systems.>>
