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 reel 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 change 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: A system for spectrometry includes an input device, a measuring device with a spectrophotometer, a calculating device and an output device for outputting results of calculations by the calculating device. The input device allows a user to input target wavelengths at which spectrometric measurements are to be carried out, character arrays representing variables assigned to measured values which are to be stored, and character arrays representing calculation formulas created according to specified rules. The measuring device serves to measure a sample spectrometrically with the spectrophotometer to obtain measured values at the inputted target wavelengths. The calculating device analyzes the character arrays representing the calculating formulas and carries out calculations of the calculating formulas by replacing any of the character arrays representing the variables, if contained in the calculating formulas, each by corresponding one of the measured values.

Abstract: A diffraction grating and a prism with the appropriate characteristics are employed to provide a combined dispersive characteristic that is substantially linear over the visible spectrum. Radiation from the grating and prism is collimated by a lens towards a detector array. The grating or a telecentric stop between the grating and prism is placed at a focal point of the lens in a telecentric arrangement so that equal magnification is achieved at the detector array. If the detector array is replaced by a plurality of optical channels, a multiplexer/demultiplexer is obtained.

Abstract: A spectrometer uses collimated, P-polarized light made incident on a surface of an optically transparent material at angle &thgr;INC. The material transmits the light which reaches a boundary surface between the input material and an output optically transparent material. The input material is preferably highly dispersive, making Snell component values at the boundary surface markedly different for different wavelengths. The output material is preferably of low dispersion and high birefringence. Only one wavelength at the boundary surface has a Snell component value tangent to its corresponding index surface in the output section. Within this section, the ray vector for this wavelength is parallel to the boundary surface. Because optical energy propagates in the ray vector direction, only the narrow range of wavelengths having ray vectors substantially parallel to the boundary surface reach an output surface of the device. This narrow range of wavelengths comprises the passband incident on a detector.

Abstract: In a spectrographic type spectrometry measuring apparatus employing a concave holographic diffraction grating or a replica thereof, a small-size and light-weight spectrometry measuring apparatus having a high reliability with a spectrum position does not move in a photo detector plane in spite of an occurrence of a temperature change. This measuring apparatus is composed of a light-condensing device, a concave holographic diffraction grating or a replica thereof, and a telecentric correction lens for condensing a diffracted light from the diffraction grating telecentrically on the spectrum condensing plane. In this constitution, the spectral ray enters vertically to the spectrum focusing plane, and if the photo detector is moved in the optical axis direction due to a temperature change, the spectrum is not moved on the photo detector surface, and it is not necessary to calibrate an optical element due to an ambient temperature change.
