Optical Bk7 Glass Diameter 3mm Ball Lens for Fiber and Optical Coupler

Product Description

>> 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 with
precise 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.
