Vacuum blackbodies
FOR CRYOGENIC OR AMBIENT

IRRADIATIVE ENVIRONMENT

INTRODUCTION
Vacuum blackbodies combine performance of traditional infrared reference
sources with specific features in order to operate in vacuum chamber, at
cryogenic or ambient temperatures. They can emit over an ultra extended
temperature range, set and controlled with high accuracy.
They consist in a vacuum compatible emissive head connected to a
controller located out of the chamber. High stability of regulation is ensured
by the 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. Temperature of
the emissive surface is measured in real time via high precision calibrated
Pt sensors.

> RCNV with 0.999 emissivity

Various principles of thermal exchanges are available to suit different
applications such as characterisation and radiometric calibration of space
borne imagers, non-uniformity correction of infrared sensors, etc...
