Abstract

Chalcogenide glass has superior optical properties in term of its transmittance in the infrared (IR) region transmittance. We have determined the composite formular of $Ge_{0.19}Sb_{0.23}Se_{0.58}$ to be the GeSbSe chalcogenide glass composition appropriate for IR lenses. The optical, structural, thermal and physical properties of the compound were measured by using Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), differential scanning calorimeter (DSC), and X-ray computed tomography (X-ray CT) respectively. We recommend that a chalcogenide glass lens for infrared optics applications be fabricated by using diamond turning machining technology in order to lower the production cost and to provide accurate control over the fabrication process.
