Germanium Plano Convex Lens 50mm Focal Length
SLGE-25-50P
The single crystal of germanium used in semiconductor is less absorption in the infrared wavelength of 2 - 20μm and it can be used as an optical element of the infrared light. It is a single lens which was made with the germanium crystal. It is used as a lens of a camera to observe the infrared, such as thermography.
◦Even though it looks like the light does not transmit because of its metallic luster, it is transmitting through a wide infrared range of 2 - 20μm.
◦The wavelength of 1.5μm or less does not transmit, so it also provides the effect of an infrared transmission filter.
◦Since the silicon lens has a refractive index of 4 or more, the lens curvature is slower then when made from standard glass.
