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 testing method for the 10.6 μm optical radiation absorption coefficient of infrared optical materials, which are mainly used for testing the 10.6 μm optical radiation absorption coefficient of infrared materials. 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 2 Laser output window, lens, semi-transparent plate (beam splitter). An important parameter characterizing the quality of such an optical device is the optical radiation absorption coefficient β at this wavelength. The 10.6μm optical radiation absorption coefficient is a basic performance parameter of optical materials and an important parameter i...
