<p>A blackbody radiometric reference (100, 200, 300, 400, 500, 600) comprising a source plate (102, 302, 402, 502, 602) or a target plate (202), metallic nanoparticles (110, 210) or other high emissivity coating disposed on the plate, and an intermediate coating (112, 212) such as paint. The plate may comprise copper, aluminum or composites thereof. Apparatus capable of functioning as a radiometric or thermometric reference (300, 400). A pre-heater or weakly-coupled area may be disposed around or adjacent a highly thermally uniform area. A groove (420) or perforations (415) extending into a front surface of the source plate defining a weakly-coupled edge portion (404) surrounding a thermally-controlled, optically-active area (402), and connected by bridges (414) or structures (526) thereto. An external probe (620) may be located near the source plate for measuring ambient temperature, for compensating for ambient temperature or for radiative load on the blackbody.</p> |
