Description

technical field [0001] The invention belongs to the technical field of optical material testing, and in particular relates to a performance testing device and a testing method for the 10.6 μm optical radiation absorption coefficient of an infrared optical material, which are mainly used for testing the 10.6 μm optical radiation absorption coefficient of an infrared optical material. Background technique [0002] With the wide application of infrared optical systems in military and civilian fields, infrared materials such as Ge, ZnS, ZnSe, and chalcogenide glass are widely used in light-transmitting devices of infrared optical systems, such as CO with an operating wavelength of 10.6 μm. 2 Laser output window, lens, translucent plate (beam splitter). An important parameter characterizing the quality of such optics is the absorption coefficient β of optical radiation at such wavelengths. The 10.6μm optical radiation absorption coefficient is the basic performance parameter of ...
