Abstract
A black molecular adsorber coating (MAC-B) composition is provided that exhibits adsorptive capabilities and reduces the effects of optical path degradation and system performance degradation when formed into a black coating having low reflectivity. The coating can be used in stray light control applications or within light paths between optical systems to absorb light and reduce the effects of optical path degradation. The coating can be used in vacuum systems to adsorb molecular contaminants and to reduce vacuum pressure levels. The coating composition can be sprayed onto interior surfaces, such as optical cavities of cameras, telescopes, lasers, baffles, detectors systems, and electronics boxes to control performance degradation due to outgassed molecular contaminants. The sprayable black molecular adsorber coating composition eliminates the major drawbacks of previous puck style adsorbers, slurry coated systems, and other bulky adsorber systems, resulting in cost savings, mass savings, easier utilization, greater adsorber surface area, more flexibility, and higher efficiency.
