Please note that this is a development product and not yet released. It is not Vantablack or Vantablack S-VIS (as the mask was previously coated with), but a new non-nanotube coating we have in development. Its total hemispherical reflectance is c.0.3% at 600nm wavelength. Unlike Vantablack, which is a free space material that doesn't tolerate handling, this is a solid coating that is far more tolerant. We thought this would be an interesting way to demonstrate its performance as nothing but…
