DCN1000 and motorized target wheel

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.

Integrated tests with LabVIEW driver 

Labview Driver available

HGH Infrared Systems provides a full-featured LabVIEW driver for its family of blackbodies, compatible with LabVIEW v8 or higher and for all available communication links Ethernet, RS232 and IEEE.

The supply includes all the required VIs directly available from the LabVIEW menu. These functions allow the operator to send a temperature setpoint, read the current temperature, check the stabilization status and many other functions.

The supply also includes an example program built with all the available VIs.

Thanks to this driver, all HGH’s blackbodies are fully controllable and can be integrated into complex test benches running automatic infrared characterization routines.
