摘要： Eine Abtastvorrichtung für die punktweise Ausmessung der Farbeigenschaften eines Messobjekts umfasst eine Auflagefläche für das Messobjekt, einen Farbmesskopf, eine Antriebseinrichtung zur Bewegung des Farbmesskopfs über die Auflagefläche in wenigstens einer Dimension derselben und zur Höhenverstellung des Farbmesskopfs in Richtung senkrecht zur Auflagefläche sowie eine die Antriebseinrichtung ansteuernde und mit dem Farbmesskopf zusammenarbeitende Mess- und Antriebssteuerung. Sie ist mit einer elektronischen Abstandsregelung ausgestattet, welche mittels der Antriebseinrichtung für jeden Messpunkt den Abstand des Farbmesskopfs über dem Messort in Richtung senkrecht zur Auflagefläche auf einen Soll-Messabstand einstellt. Die elektronische Abstandsregelung arbeitet mit vom Farbmesskopf erzeugten Messwerten und daraus berechneten Abstandswerten.
Die Abtastvorrichtung ist aufgrund ihrer spezifischen Ausbildung für die berührungslose, hochpräzise Messung auch von kleinsten Messfeldern geeignet und erfordert für die Abstandsregelung keine separaten Messfühler.

摘要： Color measurement instrument (10) including an integrating sphere (12), a beam splitter (16), a video camera (18), and a spectrograph (20). The beam splitter (16) is aligned with the viewing port (32) of the spectrophotometer to deliver the light reflected from the sample (S) to both the video camera (18) and the spectrograph (20). The video camera (18) provides an image of the position of the sample (S) with respect to the viewing port (32) of the sphere (12), enabling the visual observation and evaluation of the sample position prior to use of the spectrophotometer.

摘要： Percentage concentrations of constituents or color components of a sample are determined using a spectral analyzer with a wide illumination spot size and detector. The analyzer irradiates the sample, picks up diffuse reflectance of individual wavelengths from the sample and spatially separates the diffuse reflectance into a response at individual wavelengths. The result is to simultaneously detect the intensities of the individual wavelengths in parallel from the sample being analyzed. Percentage constituents of a composite substance can be determined or, alternatively, the components of color in a sample can be determined by analyzing wavelengths of reflected light.

摘要： An apparatus and method for utilizing NIR spectrography for measuring major constituents of substances in real time includes a monochromator (38) or other sensor having no moving optical parts. At least one of the monochromator (38) and the substance are moving relative to one another. An NIR radiation source (44) irradiates a substance (51) and the reflected or passed-through radiation is transmitted to the monochromator (38), which isolates and detects narrow portions of the received spectrum. By analyzing the intensities and wavelengths of the received radiation, the presence and amount of major constituents of the substance can be determined.
