Ultra-Black Surface CoatingThe Vantablack S-VIS ultra-black surface coating technology from Surrey NanoSystems Ltd. is being offered by Santa Barbara Infrared Inc., improving IR emissivity in the midwave-IR (MWIR) and longwave-IR (LWIR) spectral wavelengths.

Vantablack is the world’s blackest surface coating material for the UV to far-IR spectrum. It employs an innovative nanomaterial structure that absorbs virtually all incident light. Developed for spaceborne imaging applications, it offers high IR absorption and excellent thermal, mechanical and environmental stability. In the MWIR range of 3 to 5 μm, emissivity is >99.8 percent. In the LWIR range of 8 to 12 μm, emissivity is >99.5 percent.

Emissivity levels on a flat-plate blackbody source provide improved radiometric accuracy for the calibration of IR cameras. Additionally, stray light reduction in baffles for cold-shield designs and IR radiation applications will also benefit from the technology. The Vantablack coating is offered for terrestrial blackbody applications worldwide.
