Abstract: A novel scanning monochromator uses a PM stepper-motor to directly drive a diffraction grating. By employing interpolated encoder feedback in combination with the PM stepper-motor feedback, a resolution of over 250,000 pulsed steps is available for each revolution of the PM stepper-motor. This translates into more than 20,000 incremental angular-displacement steps over a usable 30° range of dispersion-element rotation. High field accuracy is achieved by a direct PM stepper-driven diffraction grating, and a unique calibration approach based on Wood's anomalies. A plurality of diffracted light beams emerge from the oscillating grating, and these are scanned past a detector for detection, whereby the relative rotation information of the grating can be detected with great accuracy. A number of tolerance-correcting measures are also included to yield an extremely accurate, self-lubricating scanning monochromator that can be economically produced.

Abstract: A spectrometer is described which comprises a dispersive element for spectrally decomposing a light beam, whose spectral distribution is to be determined, into spectral components, as well as a suspension for supporting the dispersive element and for biasing the same into a resting position with a biasing force, when the dispersive element is in a deflected position. A control means controls a holding means to vary the deflected position, so that different spectral components become detectable for a detector of the spectrometer having a first and a second detector element. A combining means combines shots made by the detector at different positions of the dispersive element.

Abstract: A wavelength variable light source emits a light whose wavelengths continuously change from a preset start wavelength up to a stop wavelength to a measuring object. A timing information output section generates timing information showing emission timings of lights emitted from the wavelength variable light source and having start and stop wavelengths and a plurality of wavelengths obtained by delimiting the wavelengths between the start and stop wavelengths in predetermined steps. A light receiving section receives the light output from the measuring object and outputs a signal showing a measured value of a received light. A plurality of amplifiers receive the signal output from the light receiving section and amplify the signal at each predetermined amplification factor. A signal selecting section selects one signal kept in a predetermined measuring range of signals amplified by the plurality of amplifiers at the each predetermined amplification factor and outputs the one signal as a measured value of a light of a wavelength decided in accordance with corresponding timing information in the information output from the timing information output section.

Abstract: A plane diffraction grating based on surface normal rotation according to the present invention is designed so that the profile of the grooves at a radial area is determined depending on a rotational position of the area about a rotational center defined as a foot of the rotational axis on the surface of the plane diffraction grating. An optical system such as a spectrometer or a monochromator according to the present invention uses such a plane diffraction grating, and requires a special arrangement. The optical system includes: a plane diffraction grating as described above; a mechanism for rotating the plane diffraction grating about the rotational axis; an incidence optical system for casting a converging beam of light on a point of the surface of the plane diffraction grating, where the point is set apart from the rotational center. As the diffraction grating is rotated about the rotational center, the point on which the incident converging beam of light is cast rotates about the rotation center, where the diffracting condition is optimized anywhere around the rotational center or for any scanning wavelength. The surface of the plane diffraction grating can be covered with a multiple-layer coating to improve diffraction efficiency. When such a multiple-layer is coated, the unit thickness of the multiple-layer coating at an area is also determined depending on the rotational position of the area about the rotational center.

Abstract: An interference filter transmission wavelength scanning photometer operable to determine the concentration of an interesting component in a sample without interference from coexisting components by measuring the light absorption of the interesting component. An angle of inclination of an interference filter varies periodically and is centered at the maximum absorption wavelength of the interesting component. The wavelength of a transmitted light is modulated due to the periodical variation of the angle of inclination. Variation in the intensity of the light transmitted through a sample is extracted by an infrared sensor as an electric signal. The time between rise and fall zero cross points of an AC component of the electric signal is determined by a microprocessor. A ratio is calculated from a full period and a half period of the AC component. The concentration of the interesting component is determined from a variation in the calculation of the ratio.
