Fused Silica features high transmission from 200nm to 2.2μm with a low coefficient of thermal expansion, making it ideal for the most demanding ball lens applications in the ultraviolet, visible, and near infrared spectra. Ball lenses are commonly used for improving signal coupling between fibers, emitters, and detectors, as well as objective lenses in endoscopy and bar-code scanning applications. Half-ball lenses simplify handling and integration.Half ball (hemispherical) lenses are ideal for applications such as fiber communication,endoscopy,microscopy,optical pick-up devices and laser interferometry and measurement.          Ball Lens                     Half-Ball Lens  Specification of our ball lens or half-ball lens: Fused Silica Ball Lens,4.0 Mm Fused Silica Ball Lens,Fused Silica Half Ball Lens,Optical Glass Fused Silica Ball Lens China Star Optics Technology Co.,Ltd. , https://www.csoptlens.com
