Abstract: Spectroscopy apparatus for spectrochemical analysis of a sample having an excitation source (60) for providing spectral light (62) of the sample for analysis. The spectral light (62) is analysed via an optical system (64-66-68) that includes a polychromator (70, 74-80) and solid state multielement array detector (82). The elements (i.e. pixels) of the detector (82) are serially read by means (84) to provide light intensity measurements as a function of wavelength. A problem is that the elements (pixels) of the detector (82) continue to accumulate charge during the serial read-out. This is avoided by providing an optical shutter (72) for blocking the spectral light (62) whilst elements (pixels) of the detector (82) are being serially read. Shutter (72) has a piezoelectric actuator which is preferably a bimorph mounted as a cantilever. It is preferably located adjacent to the entrance aperture (70) of the polychromator. Bimorph structures for the actuator and drive and protective circuit arrangements are also disclosed.

Abstract: An optical system having a first order spectral range that is usable in an optical spectrum analyzer receives an broadband optical test signal and a optical calibration signal and couples the optical signals via two optically isolated paths to separate optical detectors. First and second pairs of optical fibers, with each pair having an input fiber and an output fiber, are positioned in a focal plane of a collimating optic that has an optical axis. The fiber pairs are symmetrically positioned on either side of the optical axis with the input fibers positioned on one side of the optical axis and the output fibers positioned on the opposite side of the optical axis. The input fibers receive the optical test signal and the optical calibration signal. The output optical fibers are coupled to first and second optical detectors. An optical calibration source generates second order or greater spectral lines that fall within the first order spectral range of the optical system. A diffraction grating receives the optical test signal and the optical calibration signal from the collimating optic and separates the first order spectral components of the broadband optical test signal and passes the second order or greater spectral lines of the optical calibration signal. The first optical detector that is responsive to the first order spectral components of the optical test signal receives the optical test signal from the collimating optic and converts the optical test signal to an electrical signal. A second optical detector that is responsive to the second order or greater spectral lines of the optical calibration signal concurrently receives the optical calibration signal from the collimating optic and converts the calibrations signal to an electrical signal.

Abstract: A spectrometric instrument passes flashing light through a sample and has a linear detector operated by the computer to integrate signals for an established number of flashes to obtain an integrated unit of the signal data, from which spectral information is displayed on a monitor. Over a full spectral range, the established number is determined as that which effects a highest peak height proximately below a preselected maximum, and light source voltage is adjusted to bring the peak height closer to the maximum. For a narrower spectral range, an operating number of flashes for a unit is increased above the established number to accommodate a lower highest peak in the range. Wavelength calibration uses peaks in the light source. Corrections are made for stray light and non-linearity of detector response. Calculation of auxiliary information derived from input of auxiliary data through a touch screen is displayed on the monitor.

Abstract: Ein Gittermonochromator, speziell für Synchrotronstrahlung, mit Sägezahngitter (1) wird mit einer Bedingung für den Zusammenhang von Wellenlänge (Lambda) und Eintrittswinkel (α) betrieben, die nach der elektromagnetischen Beugungstheorie die zweite Beugungsordnung (m = 2) oder eine höhere Beugungsordnung vollständig eliminiert. Dabei ist die Kurve "Lambda (α)" etwa doppelt so hoch, wie im On-Blaze-Betrieb, hat aber bei großen Winkeln (α) ein resonanzartiges Maximum. Der Wirkungsgrad der Beugung erster Ordnung wird erhöht.

Abstract: A double-pass scanning monochromator (FIG. 1) for use in an optical spectrum analyzer (FIG. 11) includes an input optical fiber (10) for emitting an input light beam (12), a diffraction grating (16) for diffracting the input light beam (12) to produce a spatially dispersed light beam (20), a slit (24) for passing a selected portion of the dispersed light beam (20), a motor (90) for rotating the diffraction grating (16), a shaft angle encoder (92) for sensing grating position, an output optical fiber (42). The light (30) that passes through the slit (24) is directed to the diffraction grating (16) and is recombined by the diffraction grating (16) to produce an output light beam (36). The light beam (12) to be analyzed is incident on the diffraction grating (16) during first and second passes. A polarization rotation device (32) rotates the polarization components of the light beam (30) by 90° between the first and second passes so that the output of the monochromator (FIG. 1) is independent of the polarization of the input light beam (12). The output optical fiber (42) is translated by a micropositioning assembly (80) in a plane perpendicular to the output light beam (36) during rotation of the diffraction grating (16) to automatically track the output light beam (36) and to provide optical chopping.

Abstract: An improved flat field grating spectrometer for increasing the spectral resolution and usable spectral range. The spectrometer comprises an entrance slit or port (11), a concave grating (12), a field flattening lens (14) and detection means (5) encompassing the desired spectral region and capable of providing separate measurements between different regions of the spectral image plane. A second embodiment provides a beam splitter (18) (dichroic or neutral density) placed between the grating (12) and the detector (15) to divert a portion of the energy at selected wavelengths through a second field flattening lens (19) to a second detection means (13).
