An infrared wave-transmitting window radiation transfer characteristic measurement platform comprises a supporting platform, a heat insulation device, an infrared measuring instrument, a surface source blackbody, a data recorder and a platform state controller, wherein the supporting platform provides an installation base for all components, the heat insulation device is a box installed on the supporting platform and used for isolating an infrared wave-transmitting window from the external environment, and holes are formed in the two ends of the box; the infrared measuring instrument is used for measuring infrared radiation of the surface source blackbody and infrared radiation penetrating through the infrared wave-transmitting window, the surface source blackbody is located on the side opposite to the infrared measuring instrument and transmits infrared radiation to the infrared wave-transmitting window and the infrared measuring instrument through the holes in the box of the heat insulation box, the data recorder is used for recording experiment parameters and measurement results, and the platform state controller is used for controlling the temperature of the infrared wave-transmitting window and the temperature of the blackbody, acquiring data from the data recorder and calculating the radiation transfer characteristics of the infrared wave-transmitting window. By the adoption of the platform, the transmittance and self thermal radiation of the infrared wave-transmitting window in a high-temperature state are directly measured, and the defect of conventional measurement that only the transmittance of the infrared wave-transmitting window can be provided in a low-temperature state or normal-temperature state only is overcome.
