SLSI-P
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.

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

◦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.
