Abstract: A spectrophotometer for measuring light received from a sample is disclosed. The spectrophotometer includes a measurement head housing a sample and an illumination arrangement having a light source essentially continuous in the visible spectral range, formed by light-emitting diodes. The measurement head includes an illumination channel for each light emitting diode directing the light from each diode at a defined angle of incidence onto a measurement spot on the sample and a collecting arrangement capturing the light originating from the measurement spot. A spectrometer is optically connected to the collecting arrangement for splitting the captured light into its spectral components and for generating corresponding electrical signals. An electronic circuit, constructed for selectively controlling the light emitting diodes, controls the illumination arrangement and the spectrometer and processes the electrical measurement signals. A color densitometer, a variant of a spectorphotometer constructed in accordance with the subject disclosure, is also disclosed.

Abstract: The present invention provides a colorimeter apparatus for a color printer ink capable of rapidly measuring the colors of a color patch portion in an online mode. The light of a xenon light source 21 is directed via an optical fiber 22 and a condenser lens 23 to a zone through which a color patch 53 passes. Reflected light is condensed by a telecentriclens system 14 and focused on the light-receiving surface of a Linear Variable Filter 11. The light is spectrally divided by the Linear Variable Filter 11 and guided toward a linear sensor 13 via a fiber optic plate (FOP) or collimator 12. The output of the linear sensor 13 is converted to an analog signal by an analog signal generator 14 and sent to a signal processor 3. In the signal processor 3, a spectral reflectance factor is calculated based on the resulting spectral reflectivity, and a color or color difference is calculated based on this value and a prestored formula for color systems or color differences.

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.
