The earliest experimental data on an oxygen-free glass have been published by Schulz-Sellack in 1870 1]. Later on, in 1902, Wood 2], as well as Meier in 1910 3], carried out the first researches on the optical properties of vitreous selenium. The interest in the glasses that exhibit transparency in the infrared region of the optical spectrum rose at the beginning of the twentieth century. Firstly were investigated the heavy metal oxides and the transparency limit was extended from (the case of the classical oxide glasses) up to wavelength. In order to extend this limit above the scientists...
