Color Measurement on Metalized Substrates

In measurement geometry nomenclature, the first number refers to the angle of illumination and the second number refers to the viewing angle. This means that in the case of 45°/0° geometry, the light source shines at a 45° angle from the sample’s surface, and the detector receives the reflected light at a 0° degree angle from the perpendicular surface of the object (Fig. 1).
