Abstract: A manual device for the detection of photometric data which includes a measuring head to illuminate a measuring surface and to detect the light reflected. The measuring light captured by the measuring head is spectrally decomposed by a monochromator containing a diffraction grating. The intensity of the light exiting through an outlet diaphragm is detected by a photodetector. The spectral position of the measuring light is set by a drive motor rotating a grating shaft connected with the holder of the diffraction grating. From the spectra detected, densitometric and colorimetric data are calculated by a computer, which together with the spectra determined, may be displayed on a display field.

Abstract: A photodiode array spectrometer for determining the spectral composition of a plychromatic beam of radiation comprises diffraction means (10) which generate from the polychromatic beam a diffracted beam with a plurality of spatially separated diffracted rays of different wavelengths (.lambda..sub.1, .lambda..sub.2, .lambda..sub.3). A photodiode array (11) receives the diffracted beam whereby each photodiode intercepts a different spectral portion of the beam. A rotatable transparent plate (8) is provided in the beam path in front of the diffraction means (10) which, due to refraction of the beam upon entering and leaving the plate (8), permits to vary the direction of the beam impinging on the diffraction means (10) and therefore the direction of the diffracted beam in small steps depending on the angle of rotation of the plate (8). By the stepwise displacement of the diffracted beam across the photodiode array (11), a better sampling of the diffracted beam and therefore an improved spectral resolution is achieved. The invention can be used in the spectrometric analysis of a sample contained in a sample cell ( 5), whereby the sample cell is irradiated with polychromatic light from a light source (1).

Abstract: A method for the phase synchronization of equipment controlled by stepping drives, especially optical modulating systems for multiple-beam spectral photometers. Each time that the equipment is started up, a reference signal is made synchronous with a synchronizing signal which is derived from a sensor signal of the apparatus which is locked in phase with the intelligence signal. For a purely electrical correction the phasing between the intelligence signals and the synchronizing signal is set once. In the event of a phasing error between the synchronizing signal and the reference signal the reference signal is reset.

Abstract: A method for calibrating a monochromator to compensate for mechanical imperfections in its diffraction grating and grating drive assembly employs a two stage interactive procedure which permits the use of small (0.2 nm) spectral regions for the identification of emission lines. An iterative, self-consistent, discrete Fourier transform is used for the determination of multiple positioning correction terms. When the Fourier calculations are completed, the results of the calibration procedure are presented by the system to the analyst for acceptance. If accepted, the positioning error of the primary calibration line is measured, stored and used by the system to maintain a zero centered distribution of positioning errors each time the monochromator is reinitialized.

Abstract: A scanning monochromator system comprises a housing, structure defining entrance and exit apertures, and a radiation dispersing component in the housing arranged to disperse radiation passing through the entrance aperture into a spectrum for transmission towards the exit aperture. The dispersing element is directly coupled to an electromagnetic drive transducer with the assembly of a rotary component of the drive transducer and the dispersing component being mounted for rotation as a unit about a stationary axis that is perpendicular to the optical axis of the system so that a selected portion of the radiation dispersed by the dispersing component is passed through the exit aperture. The drive transducer is arranged to move a selected portion of dispersed radiation at the exit aperture over a wavelength range of at least 3000 angstroms with a reproducible accuracy of better than 0.03 angstroms in less than one second.

Abstract: This invention relates to an apparatus for calibrating a slit width among calibrating apparatuses in a monochromator.There has been the problem that, although the slit width precision of the monochromator has been an important performance item, the calibration of the slit width has not hitherto been performed.This invention employs a bright-line spectrum or zero-order light for the slit width calibration. A peak is found out from among output signals of a lightdetector (20) by means of a peak decision unit (26). The peak value is stored into a memory (28). This peak value and the output of the lightdetector (20) are compared by a comparator (32). The slit width is calibrated on the basis of the quantity of wavelength scanning till the coincidence of both the values.

Abstract: An Ebert monochromator for a spectrophotometer in which the diffraction grating is positioned off of the central optical axis of the collimator mirror by interpositioning a plane mirror between the collimator mirror and the diffraction grating. The plane mirror may be movable to select one of several diffraction gratings. By arranging the diffraction grating about an axis parallel with the central optical axis, a simple mechanical wavelength drive system with a common cam shaft driving the grating, a filter holder, and a rotatable slit plate can be provided. Further gratings may be driven from the cam shaft as may also the movable plane mirror which selects them.
