RCN Series

High temperature cavity blackbody

From visible to far infrared reference source

The RCN series high temperature cavity blackbodies are reference sources covering a wide range of wavelengths, from visible to far IR. They consist of a compact emissive head controlled by a new generation 2U electronic unit and its intuitive color touchscreen.

The cavity structure leads to incomparable uniformity and emissivity.

Integrated tests with labview driver :

HGH provides a full-featured LabVIEW driver for its family of blackbodies, compatible with LabVIEW 2019 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.
