The system of glass samples PbO- GeO2 comprising dissimilar concentrations Cr2O3 (0.2 - 1.0 mol %) was composed. Experimental densities and refractive index are used to conjecture different physical parameters such as ion concentration (Ni), mean separation (ri), Polaron radius (rp), field strength (Fi), electronic polarizability (αe), reflection loss & optical dielectric constant (ε0). The samples were delineated by XRD and Optical absorption (OA) patterns. The optical absorption spectra bands observed at about 440 and 665 nm are assigned to 4A2 → 4T1g (F), 4A2→ 2T1g transitions respectively. Additionally, a pair of weak bands at 680 and 700 nm observed due to 4A2 → 4T2g (F) and 4A2 → 2Eg (E) (spin and parity forbidden) transitions.
