Abstract

In this study, we use three glass systems of chemical composition to obtain the band pass filter, Phosphate glass 40P2O5 40ZnO(19-x)Na2O(x)Cu2O 1CaO at(x=0.5,1, 2,4,6&8mol%), Borate glass 40B2O3 40ZnO(19-x)Na2O(x)Fe2O31CaOat(x=0.5,1, 1.5 &2mol%)and Lithium borate glass 75 Li2B4O7–xCu2O-(25-x) PbO2at(x= 2.5, 5, 7.5&10mol%). The amorphous nature of the samples was investigated using x-ray diffraction. Physical properties (density, molar volume, and Hardness) and infrared (IR) measurement of the composition of the glass was studied. The spectroscopic properties of the glass are investigated in UV-Visible range-near infrared range (from300-800nm) using high accuracy spectrophotometer. We got a suitable glass composition that is close to the sensitivity of the human eye to visible light, and we can use as an optical filter such as a bandpass filter, which can be used with high sensitivity trap detector to measure photometric units.
