General Information

The single crystal of silicon used in semiconductor has low absorption in the infrared wavelength of 1.2 - 6μm and it can be used as an optical element for infrared light. It is a spherical plano convex lens that was made with the silicon single crystal. It is used as a lens for receiving infrared light and in infrared sensors.
Even though it looks like the light does not transmit because of its metallic luster, it is transmitting through a wide infrared range of 1.2 - 6μm.
The wavelength of 1.2μm 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 3 or more, the lens curvature is slower then when made from standard glass.


It is available with an AR coating to reduce the transmission loss by reflection at the requested wavelength.


Silicon lens has metallic luster so that visible light is reflected and absorbed. Because of this, no transmittance occurs.
Silicon lens without an anti-reflection coating has a loss due to surface reflection and results in transmittance of about 50%.
