Abstract
A multi-angle colorimeter employs a multi-angle mode and a symmetrical arrangement mode in an optical arrangement. Light detection on both sides of the symmetrical arrangement is performed by a single photodetector unit. The photodetector unit is used on both sides, and thus, the device becomes simpler, without any impact on individual difference in characteristics of multiple photodetector units. Conversely, elements for illumination can be used on both sides. Also in a case where multiple photodetector units are used, the size and cost of the device can be reduced with the use of a photodetector unit having a relatively low wavelength resolution as a photodetector unit to be used on one side. This enables to reduce an attitude error due to relative tilting of a measurement surface while reducing the size and cost of the device.
