Multilayer interference filter used in the infrared range of approximately 0.7 to 1000 μm.
It is a filter that controls infrared light by forming a multilayer film on optical substrates such as quartz, sapphire, Si, and Ge, utilizing the interference effect of the film. The selection of the optical substrate used takes advantage of the optical properties of the materials.
