All satellite launched nowadays share a common point: the embedment of instruments ensuring mission successPrior to any launch, the proper functioning of such instruments must be guaranteed. The use of Ground Support Equipment is required to carry out complete and advanced testing.

As OGSE, our Vacuum compatible Blackbodies are the adequate answer to this Challenge!

Discover our comprehensive range of Vacuum Blackbodies

Based on high emissive coatings, finest materials, advanced and accurate temperature regulations principles, Vacuum Blackbodies feature the best-in-class optical performances to recreate Space and Earth radiation for the instrument’s calibration.

They are compliant with ISO5 cleanliness standards, and can be operated at low-pressure (down to high vacuum) and temperature conditions generated by the thermal-vacuum chambers, from ambient to cryogenic.

DCN 1000 V

Highly uniform and fast regulating TEC-based blackbodies


Cavity blackbodies with emissivity greater than 0.999

ECN 100 V

Highly emissive resistances-based blackbodies with wide temperature range

Space programs we took part in:

Thanks to their specific design and excellent radiating performances, HGH’s Vacuum Compatible Blackbodies can easily manage the stress and extreme temperatures generated by space conditions, while providing high-end optical performances explaining why they are often chosen by Primes and Space Agencies as part of the Optical Ground Support Equipment (OGSE) used in the Assembly Integrating and Verification/Testing phases of satellite missions: dapibus leo.

What are the main benefits of our Vacuum Compatible Blackbodies?

  • Fine and accurate temperature control
  • High emissivity
  • ISO5 cleanliness standards compliance
  • Extensive choice of emitting surface
  • Electronic and fluid feedthrough configurations modularity
