BK7 Half Ball Lens, Fiber Coupling Spheres Or Collimating Lens
Overview: Half ball lens is another variant of thick biconvex optical lens, which are obtained simply by cutting ball lenses in half. Half-ball lenses are also common and can be interchanged with full ball lenses if the physical constraints of an application require a more compact design.
Like ball lenses, half ball lenses can focus or collimate light, depending upon the geometry of the input source. They are great optical components for improving signal coupling between fibers, emitters, and detectors. They are also used in endoscopy, bar code scanning, ball pre-forms for aspheric lenses, and sensor applications.
Star Optic provides half ball lenses with diameters between 0.3 mm to 100 mm, with diameter tolerance (sphericity) <0.3 µm and surface roughness (Ra) <0.007 µm. We also support custom ball and half ball lenses. The mostly frequent asked materials includes UV fused silica, BK7, ruby, sapphire and other high index glass, and germanium, ZnSe, ZnS. AR coating is also avialable upon request.
