The US space agency found Berghof’s black Optical PTFE to be the ideal material to protect the sensitive measuring instruments of its satellite from interferences.
NASA wants to send a satellite to the surface of asteroid “Bennu” in the OSIRIS-REx mission in order to explore it and take material samples. For this, the space vehicle is equipped with highly complex and accordingly sensitive optical measuring instruments (OCAMS).
In order to minimize interferences from direct sunlight or reflected scattered light when taking pictures, the NASA engineers went in search of a material that would absorb as much light as possible while reducing its thermal effects.
