Abstract

Abstract The transmission in the terahertz spectral range of crystalline fluorides of Lithium (LiF), Calcium (CaF2), Barium (BaF2) and Magnesium (MgF2), which are widely used in ultraviolet and infrared spectral optics, was studied. The spectral dependences of the absorption coefficient of these materials were obtained, in the region of 200–3000 μm a transparency zone was registered. This is of interest for the possible use of fluorides in THz devices in the millimeter range.
