Özet

Influence of barium metaphosphate Ba(PO3)(2), addictions on optical properties namely refractive index, n(D), partial dispersion, n(F)-n(C) reciprocal relative dispersion or Abbe number. v, and anomalous partial dispersion, Delta aP(gF) of a fluoride glass in the system AlF3-CaF2-MgF2- SrF2-BaF2 have been investigated. Optical properties of the glass were markedly affected by the barium and oxygen ion incorporated in the glass. Refractive index and partial dispersion increased from 1.4070 to 1.4188 and from 0.0038 to 0.0052, respectively, but the Abbe number and anomalous partial dispersion decreased from 107.1 to 80.5 and from 0.059 to 0.031, respectively when Ba(PO3)(2) content of the glass increased from 0 to 1.5 mol %.
