Abstract: A multi-angle colorimeter includes an index calculation unit that calculates, based on a predetermined calculation formula, an index corresponding to a particle diameter of a glittering material, which is used for metallic coating or pearl coating, using optical parameters used in color evaluation of the metallic coating or pearl coating on a surface of an object.

Abstract: A difference between a peak reflectance of a first wavelength component and a reflectance of a second wavelength component having a predetermined wavelength among reflectances of a plurality of wavelength components constituting reflected light in a highlight direction from a glitter material-containing coating film is set as a first difference value. Reflectance is measured of the first and second wavelength components of the reflected light in the highlight direction for the coating film corresponding to a measurement object. A first difference value is calculated by using the measurement result. A storage stores in advance correlation information indicating a correlation between the first difference value and an index value indicating predetermined physical characteristics of a glitter material contained in the coating film. An index value calculator calculates the index value of the coating film corresponding to the measurement object by using the correlation information and the first difference value calculated in the first calculator.

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.
Abstract translation: 多角度比色计在光学装置中采用多角度模式和对称排列模式。 对称布置的两侧的光检测由单个光电检测器单元执行。 光检测器单元用于两侧，因此，器件变得更简单，而不会对多个光电检测器单元的特性的个体差异产生任何影响。 相反，用于照明的元件可以在两侧使用。 此外，在使用多个光检测器单元的情况下，可以通过使用具有相对较低波长分辨率的光电检测器单元作为一侧使用的光电检测器单元来减小器件的尺寸和成本。 这能够减少由于测量表面的相对倾斜导致的姿态误差，同时减小了装置的尺寸和成本。

Abstract: 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.

Abstract: First and second measurement operations are performed according to each of a plurality of geometric conditions while keeping the geometric condition. In the first measurement operation, illumination light is radiated from a first light radiating position toward a measurement target position and spectroscopic measurement is performed on reflected light traveling from the measurement target position toward a first light receiving position. In the second measurement operation, illumination light is radiated from a second light radiating position toward a measurement target position and spectroscopic measurement is performed on reflected light traveling from the measurement target position toward a second light receiving position. The two spectroscopic measurement results are averaged. The second light radiating position and the second light receiving position are respectively disposed symmetrical to the first light radiating position and the first light receiving position with respect to a reference axis.

Abstract: A spectroscopic unit and spectroscopic device according to the present invention are provided with a filter that is provided with a plurality of optical filter elements disposed in order from the entrance side to the exit side of light under measurement and has different transmission wavelengths corresponding to entrance positions along a first direction. A first optical filter element from among the plurality of optical filter elements is tilted with respect to a second optical filter element disposed adjacently to the first optical filter element as a result of the first optical filter element being rotated by a prescribed angle with a third direction that is perpendicular to both the first direction and s second direction from the entrance side to the exit side as the axis of rotation thereof or being rotated by a prescribed angle with the first direction as the axis of rotation thereof.
