We present the results of our experimental investigation of the transmission of plates of zinc-selenide crystal doped with iron at a level of 0.23 mass % in the terahertz-frequency range and compare them with the transmission of undoped samples. We show that the presence of iron impurities in a zinc-selenide sample makes the medium more transparent in the frequency range from 0.35 to 0.5 THz. The transmission of a doped sample in this range increases to 20% compared to pure ZnSe. This result can be used in the future to create efficient devices for controlling terahertz radiation.
