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 intersect the light input through the lens module to convert polarization characteristics; a spectral module provided in one unit block to reflect and intersect 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 intersect 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 chromaticity, and an error obtained by the monochromatic light beams.

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 color measuring device includes a color difference meter module. The color difference meter module includes: a main detecting unit having an optical detecting unit configured to receive light introduced from an incident lens to generate a first current depending on a color, a first measuring unit configured to measure the first current, a sub-detecting unit having a dark detecting unit disposed adjacent to the main detecting unit and blocking the light to generate a second current in a dark state, a second measuring unit configured to measure the second current, a leakage measuring unit including a charging unit provided in the second measuring unit and charged with a predetermined set current, and measures a third current leaking from the charging unit, and a control unit that corrects the first current by reflecting the second current and the third current.
