Vacuum Blackbodies

Vacuum Blackbodies range for cryogenic or ambient irradiative environment

Our Vacuum Blackbodies combine performance of traditional infrared reference sources with specific features in order to operate in a vacuum chamber, at cryogenic or ambient temperatures. They can emit over an ultra-extended temperature range, set and controlled with the highest accuracy, thus simulating Space and Earth radiation.

A vacuum compatible emissive head is connected to our new generation controller located outside the climatic chamber. The highest stability of regulation is ensured by an optimized control of the losses through radiation and conduction.

High emissivity up to 0.999 is obtained thanks to a vacuum compatible coating on a specific surface structure of the blackbody. The emissive surface’s temperature is measured in real time via high precision calibrated Pt sensors. All your tests are run by the INFRATEST electro-optical test software.

Various principles of thermal exchanges are available to suit different applications such as the characterization and radiometric calibration of spaceborne imagers and non-uniformity correction of infrared sensors.
