PTFE from Berghof goes into space

PTFE from Berghof goes into space with the OSIRIS-REx mission

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.

“The BRDF of black PTFE is fantastic. It meets our mission requirements.”

In the end, black Optical PTFE by Berghof Fluoroplastics convinced the NASA developers and engineers. Applied on a large part of the surface of the optical instruments and other surface parts of the satellite, it now enables the measuring systems to work without interferences so that the satellite will be able to land safely on the asteroid.

The recorded images will be impressive, as has been proven even before the actual mission target, when the optical instruments recorded the Earth and the Moon together in one photograph for the first time. The result can be seen here:
