* Absolute temperature range from –75 °C to +150 °C * Differential and absolute operation modes * Extended areas up to 300 mm x 300 mm The air-cooled DCN1000N/H series and the fluid-cooled DCN1000W/L series are extended area blackbodies, with high thermal uniformity, stability and emissivity, for absolute temperatures ranging from –75 °C to +150 °C. They consist of an emissive head in which temperature is controlled via an electronic unit with real time adjusted PID regulator. The emissive head also includes a target support. The emissive surface temperature is controlled with high precision and stability at temperatures below or above target temperature. Both the target and the emissive surface temperatures are measured in real time thanks to high precision calibrated PT sensors. Various sizes of emissive areas are available to perform other applications such as thermal imager characterisation with MRTD, LSF and NETD targets, focal plane array calibration, infrared sensor non uniformity correction, etc.
