Abstract

A heavy metal fluoride glass composition range (in mol percent) consisting essentially of: (16-30)BaF₂.(8-26)HfF₄.(6-24)InF₃or GaF₃.(4-16)CdF₂.(6-24)YbF₃.(4-22)ZnF₂. In an alternative embodiment, a heavy metal fluoride glass composition range (in mol percent) comprises (16-30)BaF₂.(8-26)HfF₄.(6-24) of (0-24)InF₃, (0-24)GaF₃and (0-19)AlF₃.(1-16)CdF₂.(6-24)YbF₃.(4-26)ZnF₂. A preferredheavy metal fluoride glass produced in accordance with the present invention comprises a composition (in mol %) and comprises about 26BaF₂.18HfF₄.7InF₃.5GaF₃.10CdF₂.18YbF₃.16ZnF₂. A preferred heavy metal fluoride glass has maximum thickness of most preferably about 3 mm. Another preferredheavy metal fluoride glass comprises a composition (in mol %) and comprises about 26BaF₂.18HfF₄.12AlF₃.10CdF₂.18YbF₃.16ZnF₂.
