More Information
Summary:Colorimeter having first and second illumination units disposed symmetrically to a reference line in a prescribed plane, first and second light-receiving parts disposed symmetrically to the reference line in the prescribed plane, a calculation unit for determining color information about a measurement object, and an opposing wall that opposes the measurement object when it is measured. The opposing wall has an abutting part that abuts the measurement object when it is measured. The abutting part has a pair of first abutting parts disposed on two sides of a measurement opening to flank the measurement opening; and a pair of second abutting parts disposed on an orthogonal line orthogonal to a first-abutting-part connection line that connects the pair of first abutting parts to each other, the pair of second abutting parts being disposed on two sides of the first-abutting-part connection line to flank the first-abutting-part connection line.
