The 45 degree to 0 degree measurement geometry illuminates the sample at 45 degrees and views it

  • A.perpendicular to the sample surface
  • B.at 45 degrees on the same side as the illumination
  • C.at 45 degrees on the opposite side of the normal
  • D.from every direction at once using a sphere

Answer: A

Specular reflection at 45 degrees is directed away from the detector entirely. The geometry therefore always excludes the gloss component. There is no option to include it here. Sphere instruments alone offer the choice.
