Silicon(Si) Window

Single crystaline silicon (Si) is a chemically inert gas material with high hardness and insoluble in water. It has excellent light transmission properties in the 1-7 μm band, and it also has excellent light transmission properties in the far infrared band 30-300 μm, it is the characteristic can't found in other optical infrared materials. Silicon single crystal is usually used for 3-5μm mid-wave infrared optical components. Due to the good thermal conductivity and low density of this material, it is also a common material for making laser optics.

silicon (Si) is one of the basic optical components in optics, usually used as a protective window for electronic sensors or detectors of the external environment. It is used to separate the two sides of the environment, such as separating the inside of the instrument from the outside, so that the inside and outside of the instrument are isolated from each other, thus protecting the internal devices ,and it’s has a wide range of applications in optical systems, such as lidar, optical sensors, spectrometers and other equipment, as a light path transmission or reflection device.

Transmission curve

Silicon has high thermal conductivity and low density. Silicon is a widely used NIR material for applications in the 1.2 to 7 μm region due to its low cost and low density. Silicon is well suited for weight-sensitive applications, especially those in the 3 -5 μm range.
