Highly polished black glass is useful as a standard for gloss, low reflectance in directional/directional geometry, and also establishing the efficiency of the 'sphere zero' in specular excluded geometry using an integrating sphere. The black glass standard is mounted in a Delrin holder with cover to protect the optical surface. The standards come calibrated for total hemispherical reflectance in 8°/hemispherical geometry from 350-850 nm
