Double-Convex (DCX) Lenses, D=50.80mm, F=75.00mm, UV UV Fused Silica, United Optical Technology Co., Ltd (CAT#: STEM-OP-0764-YJL)

Double-Convex (DCX) Lenses, D=50.80mm, F=75.00mm, UV UV Fused Silica, model 110128, is manufactured by United Optical Technology Co., Ltd.
UV Fused Silica Double Convex Lenses are double convex lenses based on UV fused silica.
UV fused silica glass material has a wider spectral range (185nm-2.1μm) than K9 optical glass, has excellent transmittance in the ultraviolet band, lower refractive index, better uniformity, and smaller thermal expansion coefficient. It also has higher chemical resistance and very low fluorescence and can be used to make various optical components.

A lenticular lens focuses light into a point with a positive focal length and consists of two convex surfaces of equal radius. Commonly used in imaging relay systems and object imaging at limited conjugate distances. The characteristic is that the greater the conjugation ratio, the greater the aberration produced.
