Sometimes the use of color standards is necessary in addition to white and greyscale standards for the calibration of colorimeters and spectrophotometers. Our partner Labsphere Inc. offers sets in two sizes and different colors. In contrast to color standards based on ceramics, the Spectralon standards are reflecting light ideally diffuse, without directional components.

The calibration certificates are showing Tristimulus values, the color / UCS coordinates and the CIE LAB values.
