AI Technical Summary
Existing surface-source blackbody radiation sources have a narrow temperature range and a slow cooling rate, which cannot meet the full-temperature range calibration requirements of infrared remote sensing, detectors and other products.
The device employs an ultra-wide-range surface-source blackbody radiation source, comprising a front frame module, a radiator module, a sapphire substrate module, a heater, a rear frame module, a heat-conducting plate module, a temperature sensor module, a heat-conducting cable module, and a GM refrigerator module. By combining the heater and the refrigerator, and leveraging the thermal conductivity of the sapphire substrate, rapid heating and cooling are achieved.
It achieves calibration over an ultra-wide temperature range of 30K to 400K, improves heating and cooling rates, meets the infrared calibration requirements of products such as cryogenic remote sensors, and achieves temperature uniformity and stability of ±0.1K/min.
