In this study, we investigate the optical (linear/nonlinear) properties, mechanical characteristics, and acoustical behavior of lead borate glasses with a composition of 10ZnO–40 B2O3–(50-x) Pb3O4–xCuO, where x represents the varying concentrations of CuO (x = 0, 1, 2, 3, 5). The refractive index values, denoted as n, ranged from 2.533 for the ZBPC0 sample to 2.895 for the ZBPC4 sample. Estimations were conducted to determine the molar refraction, molar polarizability, reflection loss, and optical transmission of the samples. In the investigated glasses, both Rm (ranging from 41.855 to 43.657 cm3/mol) and αm\documentclass[12pt]{minimal}

Also, the elastic moduli values, including Young’s modulus and Bulk modulus, ranged from 322.84 to 337.12 (GPa), 293.76 to 304.96 (GPa), respectively. These results suggest that ZBPC glasses possess favorable properties for optical applications. Lastly, this study provides valuable insights into the structural characteristics of the glass samples.
