Abstract:
A colorimeter includes an integrating sphere, a light source, a light receiver and a low reflectance unit. The integrating sphere has a first aperture to be covered with a sample and a second aperture opposing the first aperture configured to allow reflected light from the sample to pass therethrough. The light source irradiates an inner wall of the integrating sphere with light. The light receiver receives, through the second aperture, the reflected light from a surface of the sample that enters the integrating sphere through the first aperture when the light from the light source is reflected by the inner wall, and is applied to the sample through the first aperture, and outputs a signal in accordance with the reflected light. The low reflectance unit is disposed around the light receiver to face an internal space of the integrating sphere, and has lower light reflectance than the inner wall.

Claim (Index 1):
A colorimetric device comprising:\n an integrating sphere having a first aperture portion and a second aperture portion, said first aperture portion forming an aperture for measurement at which a sample is disposed to cover said aperture for measurement, said second aperture portion opposing said first aperture portion and forming an aperture for receiving light configured to allow reflected light from said sample to pass therethrough; a light source unit irradiating an inner wall surface of said integrating sphere with light; a light receiving unit receiving, through said aperture for receiving light, said reflected light from a two-dimensional area on a surface of said sample that enters said integrating sphere through said aperture for measurement when said light from said light source unit is reflected by said inner wall surface, and is applied to said two-dimensional area through said aperture for measurement, said light receiving unit including an optical system and a detecting unit configured to allow a signal in accordance with said reflected light guided by said optical system; and a low reflectance unit disposed in an area around said light receiving unit to face an internal space of said integrating sphere, and having lower light reflectance than said inner wall surface of said integrating sphere, wherein an outside diameter of said low reflectance unit in plan view of said low reflectance unit from said aperture for measurement is equal to or greater than a diameter of said aperture for measurement in plan view of said aperture for measurement from said aperture for receiving light.
