摘要：

Visible rays cutoff infrared transmitting glasses in TeO2-GeO2-V2O5-PbF2 glass systems were investigated. Glasses without OH- absorption band transmitting wavelength regions from 2.0 to 5.0 nm were obtained. The addition of fluoride to these glasses and the treatment of dry-air-bubbling during melting decreased markedly absorption coefficient and reflectivity of OH- bands. Reflectivity of OH- bands increased with increasing absorption coefficient. Values of glass transition points from 520 to 540 degrees C and flow points from 560 to 580 degrees C were obtained.
