  • Patent number: 10768048
    Abstract: Spectral apparatus includes sensors that output signals indicating the respective energy amounts of a plurality of wavelength components. For each of the sensors, its reference spectral sensitivity is acquired, and an indicator indicating the reference spectral sensitivity of the sensor, is acquired. The deviation of an indicator indicating the spectral sensitivity of the sensor from the indicator indicating the reference spectral sensitivity of the sensor, is expressed by a linear function of an indicator indicating a mechanical error in the spectral apparatus. The indicator indicating the mechanical error in the spectral apparatus, is acquired to adapt a spectral sensitivity set of sensors to a signal set output by the sensors. For each of the sensors, the deviation of the indicator indicating the spectral sensitivity of the sensor from the indicator indicating the reference spectral sensitivity of the sensor, is acquired, so that the spectral sensitivity of the sensor is acquired.

  • Patent number: 10746650
    Abstract: The reflection characteristic measuring device according to the present invention is a device that includes a diffuse reflecting surface and measures a plurality of mutually different types of reflection characteristics by using a plurality of optical systems having mutually different geometries, which corrects the reflection characteristics to be measured by an error generated when light emitted from an object of measurement is reflected from the diffuse reflecting surface and illuminates the object of measurement. The reflection characteristic measuring device according to the present invention is therefore capable of reducing errors resulting from recursive diffused illumination.

  • Publication number: 20200182693
    Abstract: Observation light can be applied to a position for measurement without providing large space in a spectrophotometer, and the position for measurement can be easily known. A slit is disposed at a position optically conjugate with the position for measurement in the spectrophotometer. Light from an object to be measured passes through the slit, travels along a measurement optical path, and is subject to wavelength dispersion by a wavelength dispersing element. An observation light source is retracted outside the measurement optical path at the time of measuring a spectral spectrum. At the time of observing the position for measurement, the observation light source is inserted into the measurement optical path, and emits observation light toward the slit. Alternatively, light from an object to be measured passes through the slit, and is diffracted by a grating. The observation light source is disposed on an optical path of zeroth light.
