Fused quarts at 200nm to 2.2um has high transmittance and low coefficient of thermal expansion, which makes it an ideal choice for spherical lens with strict requirements in ultraviolet, visible and near-infrared spectral applications. Spherical lenses are commonly used to improve signal coupling between optical fibers,transmitters and detectors,as well as objective lenses in endoscopy and bar code scanning applications. Hemispherical lens can simplify the integration of the whole system
