Abstract: A spectrophotometer providing a sample measurement area of selectable size. The spectrophotometer includes a sphere defining a sample station, a lamp to illuminate the interior of the sphere and therefore the sample station, a color measurement engine including an aperture directed toward the sample station, and a measurement area size selector. The size selector includes a movable plate defining two or more holes of different sizes. The plate can be moved so that only one of the holes is aligned with the aperture to control the size of the measurement area sampled by the color measurement engine.

Abstract: A zoom lens is provided between the sample and the slit of a spectrophotometer to change the size of the image of the sample on the slit plane. The picture of the sample is taken by the zoom lens and is shown on a display screen, on which a window is superimposed. When the operator changes the location of the window, the sample is moved accordingly, and when the operator changes the size of the window, the focal length of the zoom lens is changed, whereby the size of the measurement area is changed. By changing the size of the measurement area on the slit plane while the size of the elementary photo-sensors of a photo-detector is unchanged, the resolution of the two-dimensional spectrophotometry can be changed.

Abstract: A direction-selective interferometric optical filter for spectrometric devices, at least includes an arrangement of two layered one-dimensional photonic structures. Each of the two structures contains a defect layer, and each photonic structure has a dispersion function in the energy momentum space (E, kx, ky), wherein kx and ky are momentum components of transmitted photons of the photonic structures for a defined energy (frequency/wavelength) E in the energy momentum space. Both photonic structures have opposite interfaces which are at a plane-parallel distance from one another. In this case, the dispersion functions of both photonic structures cross or intersect in the energy momentum space and produce a cut set of rays of waves on the surfaces of the dispersion functions at a particular energy, wherein a ray of waves contains waves selectively chosen through the filter at an angle, while other waves are reflected by the filter at other angles.

Abstract: An optical characteristic measuring apparatus includes an optical system, a detector, and an analysis unit. The optical system collects detection light incident from a sample. The detector spectrally disperses the detection light in plural times to generate plural pieces of detection data, the plural pieces of detection data indicating their respective spectra of detection light incident from the sample to the optical system with an optical distance between the sample and the optical system being different from each other. The analysis unit analyzes the spectrum indicated by the detection data to measure a predetermined optical characteristic of the sample. The analysis unit specifies a piece of the detection data to be used for measuring the optical characteristic based on intensity of the detection light in the plural pieces of detection data, and measures the optical characteristic based on the specified piece of the detection data.

Abstract: A method and system for performing color print quality monitoring for a color printing process, the method includes determining a calibration distance (ZCAL) between a Spectrophotometer (140) and an associated calibration patch (310) that provides a maximum luminescence value (LMAX) detected by the Spectrophotometer. The Spectrophotometer (140) is calibrated at the calibration distance by taking a color reading. A first color patch distance (Z1) between the Spectrophotometer and a color calibration patch (320) printed on a sheet (155) is determined from a first maximum color patch luminescence value (L1). A first color reading of the color calibration patch is taken and a second color patch distance (Z2) between the Spectrophotometer and a different area of the color calibration patch (320) is determined to provide a second maximum color patch luminescence value (L2). A second color reading of the color calibration patch is taken and compared with the first color reading to determine if the printing process needs adjusting.
