摘要： A high-sensitive contactless chromaticity measuring device according to the present invention, includes: a lens unit to receive light emitted from a measurement object; a light distribution unit including an optical fiber to receive the light passing through the lens unit and distribute the received light through n paths to output the light to the other side, wherein a numerical aperture is greater than a predetermined reference value, a condensing lens to reduce an incidence angle of the light output to the other side of the optical fiber to a target angle or more, and n color filters to transmit different wavelengths of the light passing through the condensing lens; and a signal conversion unit including a photodiode to convert the light transmitted from the light distribution unit into an electrical signal.

摘要： Disclosed is a color and luminance measuring device including a filter unit including a case which covers the entire device and has a light incident part formed on one side thereof through which measured light emitted from an object to be measured is incident, a measurement unit which measures luminance and a color by receiving the measured light in the case, and a filter unit which is disposed on a movement path of the measured light in the case to selectively control the luminance of the measured light transmitted to the measurement unit and transmit the measured light, wherein the filter unit reduces the luminance of the measured light to a predetermined level when the measured light has luminance of a predetermined level or higher and transmits the measured light to the measurement unit.

摘要： A brightness colorimeter having a measurement error caused by linearly polarized light, which is corrected, includes: a lens module to which light irradiated from one side is input; a polarization conversion module configured to penetrate the light input through the lens module to convert polarization characteristics; a spectral module provided in one unit block to reflect and penetrate the light input through the polarization conversion module so as to branch the light in different three directions; filter modules arranged on progress paths of the light branched in different three direction through the spectral module to penetrate monochromatic light beams having specific spectra among the light branched in the three directions; and measurement modules arranged to correspond to exit angles of the monochromatic light beams penetrated through the filter modules, to measure at least one of a brightness, a colorimeter and a defect obtained by the monochromatic light beams.
