Calibration for Reflectance Measurements

After the Spectrophotometer has been switched on, zero calibration and white calibration must
be performed before spectral reflectance measurements are taken. Zero calibration is performed
using the Zero Calibration Box (which has a reflectance of 0%) to set the zero reference point for
reflectance measurements; white calibration is performed using a white calibration plate (which
has a reflectance of approximately 100% and for which spectral reflectance data are provided as
white calibration data) to set a high-reflectance reference point for reflectance measurements.

White calibration data

The white calibration data of the White Calibration Plate are provided under the following of measurement
conditions. When the CM-3700A-U is purchased, these data are already set within the instrument.
• SAV (Measurement area: 1 x 3 mm, Illumination area: 5 x 7 mm) / Specular component : SCI
• SAV (Measurement area: 1 x 3 mm, Illumination area: 5 x 7 mm) / Specular component : SCE
