Extended Area Blackbody Sources

Our extended area sources are flat plate emitters with special high emissivity coating providing 0.96 average emissivity. Extended area sources provide large target with high radiant intensity for application where a cavity blackbody is too small. Infrared Systems Development also offers Low-Cost Thermo-Electrically cooled / Heated blackbody sources. The solid Copper Emitter plate provides superior uniformity and energy emission. Our Proprietary High Emissivity Black Coating provides greater than 0.95 uniform Emissivity from 0.8 to 30 um. A Type T Thermocouple is embedded in the emitter plate to allow independent monitoring and calibration of the surface temperature.
