Abstract

PURPOSE:To form chalocogen glass of high purity by supplying predetermined gas compounds into a reacting tube of oxide glass having been reduced of pressure and discharging the tube inside by the high-frequency power from the outside. CONSTITUTION:Gases of volatile silicon halide, for example, silicon tetrachloride and/or volatile germanium halide, for example germanium chloride, volatile chalcogen element halide, for example, disulfur dichloride, and argon are supplied into an oxide glass reacting tube of a pressure reduced state, and high-frequency power is supplied from the outside of the tube with a coil to cause electric discharge in the tube, whereby a chalocogen film is formed in the tube. The frequency and output of the high frequency applied which cause electric discharge in the tube through the coil on the outer side of the reacting tube and can generate stable plasma are selected. For example, about 1-30MHz and about 1-10KW. This blank material is heated to become solid, and the end thereof is spun under heating, whereby the infrared light transmitting body is obtained.
