The optical characteristics of several different chalcogenide bulk glasses and single core fibers were investigated. The spectral transmittance of bulk glasses was measured between 0.8 and 15 μm. A decrease in transmittance of the bulk material at elevated temperatures were shown to occur beyond 8 μm. At 100°C and a wavelength of 10.6 μm the effect was measured to be between 3.5 and 10 dB/m depending on material. Coated fibers were drawn from the bulk material and the fiber attenuation between 9.2 and 11 μm was between 6 and 30 dB/m depending on the material, coating, wavelength and fiber diameter.
