* Absolute temperature range from ambient +5 °C up to +800 °C * Large emissive area up to 1000x1000 mm * High emissivity thanks to micro-pyramidal surface The ECN100 series are extended area infrared reference sources, stabilizing high temperatures at up to +800 °C, with high uniformity. The emissive head includes an exclusive emissive surface made of micro-pyramids. The emissivity and thermal uniformity of these blackbodies are thus particularly high. Moreover, since the surface is made of such micro-cavities, these sources can be used over a wide range of wavelengths from near-IR to far IR. The main applications for these sources are calibration of sensors such as thermal imagers and line scanners, large spectral bandwidth reference source, sample emissivity or transmission measurement, real size infrared targets, etc. The robust structure of the emissive head allows for lab or field condition operations.
