Plano-Convex Lenses, D=12.70mm, F=40.00mm, Uncoated Germanium (Ge) Single Crystal, United Optical Technology Co., Ltd (CAT#: STEM-OP-0606-YJL)

Plano-Convex Lenses, D=12.70mm, F=40.00mm, Uncoated Germanium (Ge) Single Crystal, model 100514, is manufactured by United Optical Technology Co., Ltd.
Germanium Plano Convex (PCX) Lenses are plano-convex lenses based on germanium.
Germanium is an optical glass material commonly used in the infrared band. The transmission band is 2.0-16μm. It has the characteristics of high refractive index and high Knoop hardness. Germanium is inert to air, water, acid, alkali, etc. and can be used for thermal imaging and infrared imaging in harsh environments. It can be used as a substrate for a variety of optical components, such as lenses, windows, etc.

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. Germanium plano-convex lenses can be used in combination with other lenses for beam shaping, beam collimation, beam expansion, beam contraction and other different applications.
