Vantablack is the brand name for a range of spray-applied super-black coatings used for stray light suppression in visible and IR spectrum imaging and terrestrial or flight black body calibration systems. The coatings are unique in that they have an exceptionally low total hemispherical reflectance (THR) and absorb light efficiently from all photon arrival angles, both of which are critical requirements for simplifying optical system design and trapping unwanted stray light in visible and IR sensor systems. As well as exceptional optical properties, the coatings also have advantageous underlying functional properties that make them ideal for use in challenging environments like Low Earth Orbit and in camera shielding systems where optics must not be degraded over the life of the sensor. On Earth and in space, sunlight, earthlight, and moonlight cause glare, ghosting, and reduced S/N ratio in sensor systems. Vantablack coatings have demonstrated their ability to resolve these challenges in the
