BLACKBODIES

A Complete Range of Reference Infrared Sources from Vacuum Cryogenic to High Temperatures 

HGH is the electro-optical specialist providing leading-edge infrared reference sources, covering a wide range of temperatures, with extended areas or cavity shaped, operating at usual pressure conditions or dedicated for vacuum applications. Adapted to the most demanding IR sensor testing protocols, HGH blackbodies provide superior stability and certified uniformity. They are all delivered with a certificate of calibration linked to International Primary Standards. Reliable whatever the environment,  HGH blackbodies permit a quick start operation while offering extended control capabilities.

Main applications include calibration of thermographic sensors and cameras, qualification of thermal imagers and production lines of IR detectors and cores. In laboratory or on the field, they are part of the electro-optical test benches for the characterisation of complex optronic systems.

Bring the leading-edge blackbody technology to your lab for the most demanding EO testing applications!
