    Abstract: A spectrophotometer, in which an emission spectrum of the light source is measured. Based on the measured emission spectrum, a threshold is set to allow only an outstanding spectral intensity in a specific wavelength region to be greater than the threshold. Then, a ratio between the setup threshold and a peak spectral intensity in the specific wavelength region greater than the threshold is calculated. Then, an electric-charge accumulation time for a light-receiving element corresponding to a wavelength region equal to or less than the threshold is set at an upper limit of electric-charge accumulation time causing no saturation in any light-receiving element. Based on the ratio between the threshold and the peak spectral intensity in the specific wavelength region greater than the threshold, an electric-charge accumulation time for the light-receiving element corresponding to the specific wavelength region greater than the threshold is set.

    Abstract: The differences between the center wavelength and half bandwidth of the spectral sensitivity of each pixel of a sensor array in a spectral analyzer to be calibrated and the preprovided respective standard values of the center wavelength and the half bandwidth are expressed as functions of a pixel number (linear functions), and coefficients that define the functions are determined based on the pixel outputs of the sensor array obtained by measuring predetermined wavelength standards. The center wavelength and half bandwidth of each pixel are estimated from the differences obtained from the functions with the determined coefficients and the standard values.

    Abstract: A diffraction grating and a prism with the appropriate characteristics are employed to provide a combined dispersive characteristic that is substantially linear over the visible spectrum. Radiation from the grating and prism is collimated by a lens towards a detector array. The grating or a telecentric stop between the grating and prism is placed at a focal point of the lens in a telecentric arrangement so that equal magnification is achieved at the detector array. If the detector array is replaced by a plurality of optical channels, a multiplexer/demultiplexer is obtained. A one or two dimensional detector array may be used for detecting the characteristics of a radiation beam. Alternatively, a one or two dimensional array of optical channels may be employed in a multiplexer or demultiplex arrangement with a single output/input optical channel.

    Abstract: A method for determining spectral characteristics of an object is disclosed. A probe is positioned in proximity relative to the object and provides light to a surface of the object and receives light from the object. One or more critical heights are defined below which no specularly refelcted light is received and propagated. Prior to positioning the probe in proximity relative to the object, a plurality of position-sensitive calibration/normalization reference and a plurality of calibration/normalization measurements are taken with the probe at a plurality of predetermined positions with respect to the calibration/normalization reference. The intensity of light received is determined in a plurality of spectral bands with one or more measurements. The spectral characteristics of the object are determined based on the one or more measurements and based on data taken from one or more of the calibration/normalization measurements.

    Abstract: A color luminance meter 1 is provided with a polychrometer 4 as a spectral optical system including a light receiving sensor array 43, a signal processing circuit 5 and an operation control unit 6. The operation control unit 6 carries out calculations to obtain characteristics of a measurement light based on a specified spectral responsitivity, using light reception signals and specified weighting coefficients. The spectral responsitivities of light receiving sensors constructing the light receiving sensor array 43 are selected such that B≧5 nm and A/B lies within a range of 1.5 to 4.0 when A, B denote the half power band width of the spectral responsitivities and a center wavelength interval of the spectral responsitivities. Accordingly, there can be provided a light measuring apparatus capable of maximally suppressing errors to highly precisely measure color luminance values and the like even in a measurement of a light lying in a narrow band such as a monochromatic light.
