硅&鍺窗片

Silicon crystal windows are used primarily for light in the infrared region of wavelengths of 6μm or less. It has about 50% transmission in this range from 1.2 to 7µm,we usually add an AR coating to enhance the performance from 3-5µm. it is not suitable for CO2 transmitting optics dut to its absorption. It is useful in systems where weight is a concern.
