Abstract: A system and method for full width scanning color analysis of a printed media sheet are disclosed. The full width array spectrophotometer system includes one or more substantially linear elongated illumination arrays of closely spaced multiple illumination sources. The sources include sets of illumination sources, including a first set of different color illumination sources and a second set including one or more UV-emitting illumination sources. The sets are arranged to span a printer paper path or other object path to illuminate a band extending transversely across a printed print media sheet or other object moving in the path. A full width array light imaging sensor includes an elongated array of multiple closely spaced photodetectors for detecting plural colors and is positioned adjacent to and extending substantially parallel to the linear array(s) to receive radiation reflected from the transverse illuminated band.

Abstract: The present invention provides a flame atomic absorption spectrophotometer in which, when a flashback may occur, a continuous use of this apparatus through an easy operation by a user is prohibited, so that the apparatus cannot be used unless its safety is confirmed. In this apparatus, when a flashback occurrence detector 23 detects that a flashback has occurred while the flame was burning, it extinguishes the flame in accordance with a predetermined extinction sequence, sets a flashback occurrence flag to be “1,” and increments a flashback count value. Even if an ignition button 26 is pressed, an ignition is not allowed if the flashback occurrence flag is “1.” When a password that was issued after the safety was confirmed by the manufacturer is entered through an operation unit 41, a password verification unit 40 in a personal computer 4 obtains a flashback count value. If the reference password which corresponds to the flashback count value and the entered password match, an apparatus controller 20 resets the flashback occurrence flag to cancel the state where an ignition is inhibited. When the flashback count value becomes equal to or more than a predetermined value, the apparatus must be sent to the manufacturer with a request for examination and possible repair, since no reference password is available.

Abstract: In a Raman spectroscopy apparatus, exciting light is focussed on a sample (26) as a line focus 38. Spectra from points in the line focus are dispersed in rows 46 on a CCD detector 34, having a two-dimensional array of pixels. The line focus moves longitudinally in a direction Y (arrow 48) relative to the sample. Simultaneously and synchronously, charge is shifted in a parallel direction Y′ (arrow 50) within the CCD, so that data from a given point in the sample continues to accumulate. This ensures that the data from each sample point arises from illumination which is integrated along the line focus, and makes it easier to stitch the data together subsequently to form an image of the sample. In order to provide averaging in the X direction during fast, low resolution scanning, the line focus is swept across the sample in a zig-zag fashion, between boundary lines 60.

Abstract: The present invention compensates a fluctuation of a light-emitting intensity of a light source. First splitting portions (12, 13) in the present invention are used to split lights emitted from the light source, and an excitation light with a specific wavelength (λEx) is incident to a sample element 15. Second splitting portions (16, 17) are used to split the lights from the sample element portion, and a fluorescence detecting portion 18 is used to measure the fluorescence intensity (IEm). A reference light detecting portion 19 detects a specific wavelength (λR) of the lights without being selected by the first splitting portion, and then the light intensities detected by the reference light detecting portion are outputted and stored in a spectrum data storage portion 21. The intensity (IEx) of the excitation light is calculated according to the wavelength of the excitation light, the wavelength of the reference light, and the intensity of the reference light in the spectrum data. An output of the fluorescence spectrophotometer is calculated through the measured fluorescence intensity (IEm) and the calculated intensity (IEx) of the excitation light.

Abstract: A spectrograph including a primary mirror, a secondary mirror, and a tertiary mirror forming a TMA having a common vertex axis. The spectrograph also may include a collimating mirror, a diffraction grating, and a dispersive prism. The collimating mirror and an entrance aperture form an interchangeable module. Radiation received through the entrance aperture is reflected in a collimated pattern towards an aperture stop. The diffraction grating, located between the collimating mirror and prism, diffracts radiation passed through the aperture stop into multiple beams directed onto the prism. A flat mirror, located to one side of the vertex axis. receives and reflects the multiple beams exiting the prism onto the primary mirror, where they are reflected onto the secondary mirror. The secondary mirror reflects the beams to the tertiary mirror where they are reflected onto an image plane located on the other side of the vertex axis.
