ABSTRACT

The glass of BaO-GeO2-La2O3-ZnO system with a transmittance of more than 75 % at mid-wave infrared (MWIR) region in the range of 3 μm to 5 μm is manufactured and its property is evaluated. After selecting construction that can melt glass through flow button test, BaO-GeO2-La2O3 system where 10 mol%, 20 mol% of ZnO were added respectively were melted at 1350°C for 1 hour and BaO-GeO2-La2O3 system of glass was manufactured. Among them, with 20 mol% of ZnO, 16 mol% BaO-56 mol% GeO2-8 mol% La2O3-16 mol% ZnO system of glass was found to has less than 660°C of glass transition temperature, more than 1.70 of refractive index, and more than 530 of knoop hardness. Therefore, it is concluded that glass of BaO-GeO2-La2O3-ZnO system of glass with 20 mol% ZnO has good melting conditions at low temperatures and excellent optical properties, thus, can be utilized for special optical materials field.
