Plano-Convex Lenses, D=12.70mm, F=40.00mm, Uncoated Silicon (Si), model 100490, is manufactured by United Optical Technology Co., Ltd.
Silicon Plano Convex (PCX) Lenses are plano-convex lenses based on silicon.
Silicon is a commonly used optical glass material in the infrared band. The transmission band is 1.2-8.0μm. Silicon has high thermal conductivity. It can be used as the substrate for a variety of optical components, such as lenses, windows, etc. It is often used in near-infrared and mid-infrared applications, and is also suitable for infrared imaging, terahertz imaging, medical, military and other applications.

Plano-convex lenses focus light into a point. Its characteristic is that 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. Silicon plano-convex lenses combined with other lenses can be used for different applications such as beam shaping, beam collimation, beam expansion, and beam contraction.
