This study explores the compression molding of diffractive-aspheric lenses using GeSbSe chalcogenideglasses. A mold core with diffractive structure was prepared and a chalcogenide glass lens was molded atvarious temperatures using the corresponding core. The effect of molding temperature on the transcriptioncharacteristics of diffractive structure was examined, by measuring and comparing the diffractive structurebetween the mold core and the molded chalcogenide glass lens using a microscope and a white lightinterferometer. In addition, the applicability of the molded lens for thermal imaging was evaluated, bymeasuring the form error.
