    Abstract: The invention relates to a spectrometer, which comprises a suspension mechanism (3) for its dispersive element (2), said suspension element pretensioning the spectrometer in an idle position, in addition to a deflecting device, which retains the dispersive element (2) in a deflected position, in such a way that a balance of forces occurs between the retaining force and the pretensioning force. This permits the dispersive element (2) to constantly return to the position defined by the retaining force after impacts or vibrations. An inventive spectrometer therefore comprises a dispersive element (2) and a suspension mechanism (3) for bearing the dispersive element (2) and for pretensioning the latter in an idle position using a pretensioning force, if the dispersive element (2) is in a deflected position. A control device (7) controls a retaining device (6a, 6b), to vary the deflected position, so that different spectral components can be recorded by a detector (9) of the spectrometer.

    Abstract: An interference filter transmission wavelength scanning photometer wherein the angle of inclination of an interference filter (3) is periodically varied, the wavelength of the light to be transmitted is modulated with the periodical variation centered at the maximum absorption wavelength of the component to be measured, the variation of the intensity of the light transmitted through a sample is extracted by an infrared sensor (11) as an electrical signal, the time between the rise and fall zero cross points of the AC component of the electrical signal is determined by a microprocessor (16), the ratio (full period - 2 x half period)/(full period) is calculated from the full and half periods determined from the determined time, and the concentration of the component to be measured is determined from the variation of the result of the calculation of the ratio, thereby quantitatively determining the component without being influenced by the disturbance coexistent components.

    Abstract: The present invention concerns a spectrometer comprising means for producing a parallel beam from a light source whose spectrum is to be measured and directing it to an orientable grating (10) which produces a diffracted beam, means for focusing said diffracted beam to a detector (18) which measures the power of a selected line of the spectrum (1), said means comprising a reflector (12), and means for measuring the wavelength of the selected line.
    The means for measuring the wavelength comprise a reference light source producing a reference spectrum (3), comparison means for comparing the wavelength of the measured reference spectrum (1) with the stored reference spectrum (3), means for rotating the grating (10) providing a coarse positioning of the diffracted beam relatively to the detector (18) and measuring the grating position, and means for rotating the reflector (12) providing a fine positioning of the diffracted beam relatively to the detector (18) and measuring the reflector (12) position.

    Abstract: Light under measurement whose wavelength is continuously swept is incident on fiber-opticEtalon. The fiber-opticEtalon transmits the light under measurement each time the wavelength of the light under measurement satisfies specific conditions. A PD detects the transmitted light of the fiber-optic Etalon and outputs the intensity of the light under measurement. A counter counts the number of peaks of the output of the PD. A CPU calculates the wavelength of the light under measurement based on the count value of the counter.

    Abstract: A grating drive apparatus (100) for use in a multiple-grating spectrometer (500) is provided. The spectrometer has an entrance slit (521), an exit port (550), an optical path (525) between the entrance slit and the exit port, and a plurality of diffraction gratings (237-239). Each of the gratings is rotatable about a respective preferred axis for selecting a wavelength during spectrometer operation. The grating drive apparatus includes a turret (200) having a plurality of gratings mounted on it, a mechanical stop assembly (300), and a drive assembly (400). The drive assembly causes the turret to engage the stop assembly to rotate the turret and select a grating. The drive assembly also rotates the selected grating to select an operational wavelength.
