Plano-Convex Lenses, D=12.70mm, F=40.00mm, UV UV-Grade Fused Silica, United Optical Technology Co., Ltd (CAT#: STEM-OP-0483-YJL)

Plano-Convex Lenses, D=12.70mm, F=40.00mm, UV UV-Grade Fused Silica, model 100416, is manufactured by United Optical Technology Co., Ltd.
UV Fused Silica Plano Convex (PCX) Lenses are plano-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, 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. Fused silica plano-convex lenses focus light into a point.

The focal length is positive, one side is flat and the other is convex. Often used for aiming and focusing monochromatic light sources. When in use, face the convex surface towards the incident light. UV fused silica plano-convex lenses combined with other lenses can be used for different applications such as beam shaping, beam collimation, beam expansion, beam contraction, etc.
