Faraday’s Robust FARADAYIC® CNT Based Coating for Scattered Light Suppression
Faraday Technology Inc., a wholly owned subsidiary of Physical Sciences Inc. (PSI), has been awarded a contract from The National Aeronautics and Space Administration (NASA) to develop an approach to scalably apply carbon nanotube based black coatings to large area surface and demonstrate the coating’s potential to suppress scattered light, withstand launch conditions, and resist radiation effects and atomic oxygen erosion.
Low reflectivity surfaces are required for numerous space-borne instruments, such as telescope housings and baffles, for reducing stray light from optical payloads in order to improve image resolution and clarity for a number of future NASA missions. Thus ow reflective black coatings need to be developed for suppressing scattered light across visible-near infrared wavebands. Furthermore, the coatings should withstand launch conditions, resist radiation effects, and resist atomic oxygen erosion. Faraday, is collaborating with Aerospace Corporation and Physical Sciences Inc. to develop this approach. The materials and technology enabled by this work are anticipated to provide significant benefit to future NASA missions requiring suppression of scattered light, as well as to earthbound entities seeking low reflective surfaces for advanced optical instruments or systems.
NASA and their prime contractors for space missions would utilize this technology. The applications include optical components where broadband absorption of electromagnetic radiation is critical, including for detectors and high-sensitivity optical systems. Solar coronagraphs and space-borne instruments, for example telescope housings and baffles, require stray light reduction. In addition to NASA’s space missions, availability of black optical coating technology may open up new markets such as military applications including missile seeker, surveillance, night vision cameras, thermal imaging, and shielded windows. We also envision other applications for this technology including: electronics and telecommuni-cations, semiconductors, solar panels, automobile industry or any other technology that suffers from scattered light reflection.
