    Abstract: A spectrometer or multiple wavelength absorbance detection method and apparatus providing improved accuracy for an array of measurements at different wavelengths. The spectrometer utilizes a multiple wavelength illumination system with an array of independent detectors with different pathlength cells, where each cell is illuminated with predominately monochromatic light after separation by a light dispersing element. Each sample cell has an optical pathlength, optics and photodetection device that are optimized for its particular wavelength to accurately measure absorbance through an expected substance.

    Abstract: A spectrophotometric system includes a zoom lens assembly that is mounted for axial translation relative to an integrating sphere. The zoom lens assembly includes first and second focusing lens mounted to an axially movable lens carrier. The lens carrier is positioned intermediate first and second sets of mirrors for reflecting/directing SCE and SCI beams toward fiber ports. A reference beam is also emitted from the integrating sphere and transmitted to a processor, thereby resulting in simultaneous tri-beam measurements. The disclosed spectrophotometric systems may also include an aperture plate detection assembly and/or a sample holder assembly that incorporates a dampening gas spring. The aperture plate detection system includes a detection disk that may include a plurality of pre-positioned sensors that interact with an activating ridge formed on the aperture plate for identification thereof.

    Abstract: An optical measuring arrangement, particularly for quality control in continuous material flow processes, comprising a measuring head which is arranged immediately adjacent to a measurement object, a measurement light source which is held at the measuring head for illuminating a measurement spot on the measurement object, a measurement light reception device, at least one spectrometer which is optically coupled with the measurement light reception device via a light-conducting device, wherein the spectrometer and the light-conducting device are received in the measuring head, and a signal processing device which is likewise received in the measuring head. This results in a compact arrangement for reflection measurement which is easy to assemble and which, beyond this, supplies very accurate measurement results. Further, a measuring arrangement operating on the principle of spectroscopy is suggested for transmission measurement. The disclosure further relates to a combined reflection and transmission measurement device which carries out both measuring processes simultaneously.

    Abstract: A color spectrophotometer incorporating a low cost commercial imaging chip, which normally forms part of a document imaging bar used for imaging documents in scanners, etc., having multiple photo-sites with three different rows of color filters. Each chip is mounted on the optical axis of an imaging lens system, in the image plane of that lens system, to image the reflected illumination from an illuminated color test target area on the chip. The optical axis of the imaging lens system is oriented at 45null to the illuminated color test patches, and the photodetector chip is physically mounted perpendicular to the plane of the illuminated color test patches. Respective photo-sensor chips and associated 1:1 optics may be mounted on opposing sides of the spectrophotometer physically oriented at 90null to the test target area plane receiving the reflected light from the test target optically oriented at 45null to the illuminated test target.
