Abstract
A heavy metal fluoride glass composition range (in mol percent) consisting essentially of: (16-30)BaF2.(8-26)HfF4.(6-24)InF3 or 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)GaF3 and (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.
