Abstract
With the recent development of less costly uncooled detectors technology, expensive optics are among the remaining significant cost drivers. As a potential solution to this problem, the fabrication of IR lenses using chalcogenide glasses has been studied in recent years. We report on fabrication of molded chalcogenide-glass lens for car night-vision and on the evaluation of the lens. The moldability of chalcogenide glass was characterized through transcription properties of the mold’s surface. In addition, both IR transmittance and XRD patterns of the molded chalcogenide glass lens were evaluated to verify the compositional and structural stability of the glass material at the corresponding molding condition.
