Ultra-black coating

Ultra-black coating

SBIR and Acal BFi announce a new ultra-black surface coating technology that improves infrared emissivity in the midwave-infrared (MWIR) and longwave-infrared (LWIR) spectral wavelengths. In the MWIR (3-5 µm), emissivity is > 99.8% (± 0.1 %); in the LWIR (8-12 µm) emissivity is > 99.5% (± 0.15%). Developed for space-borne imaging applications, Vantablack surface coating material offers exceptional IR absorption and excellent thermal, mechanical and environmental stability. The new material was recently deployed on an Earth-observation satellite.
