> Infrared validation test equipment INTRODUCTION The DCN1000W/L extended area blackbodies are low temperature infrared reference sources operating either in absolute or differential mode. Featuring the highest available stability of regulation, they are particularly well adapted for the characterization and performance validation of a very wide range of IR sensors, such as high resolution cameras for thermography, and long range thermal imagers. They consist of an emissive head of various sizes whose temperature is accurately controlled via a 2U electronic unit through an ergonomic interface and whose heat dissipation is ensured by water (W type) or a refrigerated liquid (L type). The liquid is supplied by a separate cooling liquid unit and circulated through a jacket at the back of the blackbody. The temperature of the high emissive surface is stabilised within 0.5mk at temperatures above and below ambient temperature. In order to avoid dew condensation on low temperature surfaces, the system includes several options such as sweeping dry gas on the emissive area, enclosing the emissive area inside a nitrogen filled chamber sealed by an IR window, coupling the blackbody to a nitrogen filled cabinet housing the unit under test. Just as any other HGH blackbody, the DCN1000W/L family are provided with a radiometric certificate of calibration demonstrating the reliability of this IR reference source for two years. Targets can be added, as well as the INFRATEST software, thanks to which a wide range of tests can be automated: NETD, temporal noise, fixed pattern noise, MTF, FoV, distortion, spatial resolution, MRTD, TOD, etc. BENEFITS • Extended areas up to 300 mm x 300 mm • Differential and absolute modes operation • Real time display of temperature data • Intuitive interface • The highest stability: <0.5mk • High thermal uniformity and emissivity • Built-in test equipment (BITE) • Compact emissive head • Absolute temperature range from –40 °C to +150 °C • Control through coloured touchscreen panel • Radiometric calibration over multiple bandwidths • Remote control via Ethernet link, RS232, IEEE488, WiFi • Infratest - LT control software OPTIONS • Double-head option (W4/L4 only) • Targets for NETD, LSF/MTF, MRTD, distortion, etc • Motorised target wheel and multiple accessories • Enhanced emissivity >0.99 • NETD, LSF/MTF, MRTD and TOD calculation software • Anti frost and condensation system • LabVIEW drivers for all commu
