Homogeneous glass samples with different compositions of (99−x) [(Na2O)(P2O5)]–[1ZnO]–x[CuO] (where x = 0, 1, 2, 3, and 4 mol%) were prepared under controlled conditions using the conventional melt– quenching technique. The structural characteristics of the prepared glass samples were investigated using X-ray diffraction (XRD) analysis, confirming their amorphous nature. The optical properties, including transmittance and absorbance, were measured over the wavelength range of 190–2700 nm using a Jasco V-670 UV–Vis–NIR spectrophotometer. Based on the obtained optical data, several optical parameters were calculated, including reflectance, refractive index, optical basicity, absorption coefficient, extinction coefficient, real and imaginary parts of the dielectric constant, optical conductivity, and permittivity. Furthermore, a detailed theoretical analysis was performed to interpret the observed spectral features and absorption behavior. The results demonstrate that this glass system exhibits promising optical characteristics, highlighting its potential applicability in optical filter and photonic applications.
