Interference Filter
The interference filter is fabricated by alternately depositing multiple layers of media films with different refractive indices on a glass substrate. By utilizing the interference effect when light reflects and transmits between these layers, it selectively allows light of specific wavelengths to pass through while suppressing light of other wavelengths. It is widely applied in optical instruments and spectral analysis, laser and optical communication, biomedical and imaging, industrial and environmental monitoring, etc.
