Terahertz Optical Filters
High-transmittance THz bandpass filters are mainly used for terahertz spectroscopic detection, THz imaging, THz material inspection and THz sensing. THz low-pass filters are components that transmit THz waves while blocking shorter wavelengths. They are made from packaged special materials and operate on the principles of dispersion, reflection, scattering, diffusion, diffraction and interference. Their main applications include THz imaging, THz test equipment, materials research, astronomy and aerospace.
