    Abstract: A surface temperature measuring apparatus includes a radiation thermometer (11) that measures a surface temperature (Tm) of a measurement range larger than a measurement target region of a measurement target (100), the radiation thermometer (11) detecting, by a sensor, an infrared ray radiated from an object surface of a specified measurement range to measure a surface temperature of an object, a second temperature measuring means (11) that measures a surface temperature (Tn) of a region outside the measurement target region of the measurement target (100) but within the measurement range of the surface temperature (Tm) by the radiation thermometer (11), or a region having an identical or substantially identical temperature to a temperature of the region outside the measurement target region, and a correcting means (12) that corrects the surface temperature (Tm) that is measured using the surface temperature (Tn) that is measured into a surface temperature (T) of the measurement target (100).

    Abstract: A wavelength of incident light is measured based on signals from a plurality of pixels of a photoelectric conversion element that are arranged in a dispersion direction in which the incident light is dispersed by a spectroscopic section. In correction of a shift in wavelength, a measured amount of shift in wavelength that is a difference between a measured value obtained when an emission line wavelength of incident light from a light source for wavelength shift correction that emits light including an emission line at least one wavelength in a range of wavelengths into which light can be dispersed by the spectroscopic section is measured and an original emission line wavelength is calculated. A reference amount of shift in emission line wavelength is calculated by a polynomial in which a characteristic of a wavelength shift that occurs is represented by a linear or higher polynomial with a variable indicating the wavelength or a parameter relating to the wavelength. Each coefficient of the polynomial is determined based on the calculated measured amount of shift in emission line wavelength and the reference amount of shift in emission line wavelength, and the wavelength of the incident light is corrected based on the determined polynomial.

    Abstract: An optical characteristic measurement device has a measurement opening, includes a first optical measurement unit and a second optical measurement unit that measure different optical characteristics with different geometries with respect to a measurement target facing the measurement opening, and further includes a processing unit that corrects a measurement value obtained in the second optical measurement unit based on a measurement value obtained in the first optical measurement unit. The first optical measurement unit includes an illumination optical system that illuminates the measurement target facing the measurement opening, a first light receiving optical system that collects light reflected by the measurement target, and a first light receiving unit that receives light collected by the first light receiving optical system and outputs the light as a measurement signal, and has a diffuse reflection surface that diffuses and reflects incident light to the illumination optical system or the first light receiving optical system. The second optical measurement unit includes a light projecting optical system that projects light from a direction inclined by a predetermined angle with respect to a normal line of a measurement surface of the measurement target facing the measurement opening, a second light receiving optical system that collects light reflected by the measurement target in a regular reflection direction, and a second light receiving unit that receives light collected by the second light receiving optical system and outputs the light as a measurement signal.

    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. The observation light source emits observation light toward the grating at the time of observing the position for measurement.

    Abstract: Provided is a compound optical system that can obtain high-resolution images by solving the problem of aberration in a field-of-view separation-type optical system, and that enables a super thin image pickup device to be achieved. Also provided is an image pickup device using the compound optical system. With respect to the image pickup range of a central individual-eye lens, by narrowing the image pickup range of a peripheral individual-eye lens, the field curvature amount at the image pickup region can be reduced, and therefore, the eccentricity amount of the lens surface (or the lens group) can be reduced. As a result, an individual-eye lens with little defocus and good image forming characteristics can be obtained, and a compound optical system with favorable image forming characteristics can be configured.

A light distribution measuring apparatus includes the ultraviolet optical system and a sensor, and outputs light distribution of the ultraviolet light source by using a signal obtained by the sensor. The ultraviolet optical system is positioned such that the intermediate image is re-imaged on a light receiving sensor surface, and the sensor has light receiving sensitivity to ultraviolet light having a wavelength of 300 nm or shorter.

    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.
