Ball Lenses

Simplify optical fiber and laser collimating and focusing systems - without sacrificing performance - with these precision ball and half ball lenses.

A carefully controlled fabrication process enables Coherent to consistently make spheres with precise diameters and unsurpassed surface quality, making them ideal for fiber communications, endoscopy, microscopy, laser measurement systems and more.

Ball Lens Capabilities

Choose full spherical and hemispherical lenses over a range of sizes; larger spheres are easier to handle and reduce sensitivity to misalignment.
