Silicon Window

Silicon is another material that is frequently utilized in infrared systems – however due to absorption it is not suitable for CO2 transmitting optics. Silicon can be used from 1.2 to 7μm but only has about 50% transmission in this range. Because of this, we have added an AR coating to enhance the performance from 3-5μm. With a density of 2.329g/cm3, Si is ideal for use in systems where weight is a concern.
