Ball Lenses, D=7.00mm, F=5.57mm, Uncoated UV Fused Silica, United Optical Technology Co., Ltd (CAT#: STEM-OP-2663-YJL)

Ball Lenses, D=7.00mm, F=5.57mm, Uncoated UV Fused Silica, model 160016, is manufactured by United Optical Technology Co., Ltd.
Ball lenses are primarily used in fiber optic applications because their short back focal length minimizes the distance required from the ball lens to the optical fiber. UV fused silica glass material has a wider spectral range (185nm-2.1μm) than K9 optical glass, and has excellent transmittance in the ultraviolet band. It has a lower refractive index, better uniformity, and a smaller thermal expansion coefficient. It also has higher chemical resistance and very low fluorescence, and can be used to make various optical components.
