Abstract: In a fluorescence spectrophotometer a first spectrum of fluorescence emitted by a sample in a state where the wavelength of excitation light is fixed to an arbitrary wavelength; a second spectrum of fluorescence emitted by the sample in a state where the wavelength of excitation light is changed to another wavelength; and the wavelength when corresponding peaks in the two spectra are approximately in accordance with each other is set for the fluorescence wavelength emitted by said sample.

Abstract: A method and apparatus for the qualitative and quantitative spectroscopic investigation of elements present in a liquid sample using the laser spark. A series of temporally closely spaced spark pairs is induced in the liquid sample utilizing pulsed electromagnetic radiation from a pair of lasers. The light pulses are not significantly absorbed by the sample so that the sparks occur inside of the liquid. The emitted light from the breakdown events is spectrally and temporally resolved, and the time period between the two laser pulses in each spark pair is adjusted to maximize the signal-to-noise ratio of the emitted signals. In comparison with the single pulse technique, a substantial reduction in the limits of detectability for many elements has been demonstrated. Narrowing of spectral features results in improved discrimination against interfering species.

Abstract: A method and apparatus for standardizing spectral line intensities in a spectral monochromator separate an input beam into a sample spectral line characteristic of a sample element, a reference spectral line, a standard spectral line and a background spectral band. At a first point in time an intensity I.sub.A of the sample line, a first intensity I.sub.R1 of the reference line and a first intensity I.sub.B1 of the background band are measured. At a second point in time an intensity I.sub.S of the standard line, a second intensity I.sub.R2 of the reference line and a second intensity I.sub.B2 of the background band are measured. An intensity ratio IR defined by the formula ##EQU1## is computed wherein the intensity ratio IR represents a standardized intensity of the sample line compensated for source fluctuations.

Abstract: An optical position-measuring sensor has a monolithic structure which includes at least two masses of photoluminescent material, which on excitation emit photoluminescent light with non-identical spectra. The at least two masses are supported in the sensor by a resilient part (e.g. a beam or diaphragm), the deflection of which determines the wavelength distribution of the luminescent light which is coupled into an optical wave conductor (e.g. a light fiber) terminating in the sensor.

Abstract: An optical partial pressure gas analyzer employs an electron beam to excite the outer electrons of gas atoms or molecules, and one or more photomultiplier tubes or other similar detectors to detect wavelengths of photons characteristic of the decay of the outer electrons of one or more species of gas molecules. The photomultiplier tubes have a viewing direction substantially at right angles to the electron beam. A Faraday trap or similar device is employed to avoid secondary electron generation. Thin-film interference filters are favorably employed to pass a specific characteristic wavelength of the desired species, and to reject other wavelengths. An electromechanical filter changer permits each photomultiplier tube to analyze two or more gasses alternately.

Abstract: A spectrophosphorimeter with a single spectrometer so as to obviate the need of a couple of spectrometers of conventional spectrophosphorimeters, wherein one spectrometer is operated as an excitation-side spectrometer only when the light is allowed to pass a light interceptor, and the other spectrometer works as a phosphorescence-side spectrometer only when the light is substantially interrupted. The single spectrometer is used on the excitation side when the light is allowed to pass and on the phosphorescence side when the light is interrupted.

Abstract: A fluorescence spectrometer for multielement analysis including a source for atomizing a dispersed sample along an axis and a plurality of energizers and detectors preferably arranged in pairs about the source, with each of the pairs designed for analyzing one element. Preferably, the source is an inductively coupled plasma. Means is provided for each of the pairs to view a different segment of the source along its axis, depending on the element to be analyzed. Preferably, such means includes: a source movable along its axis; fiber optics interposed between the energizers and the source and between the source and the detectors; and a movable optical element interposed between the energizers and the source and between the source and the detectors. The spectrometer further features a polychromator for use in lieu of matched optical filters in the detectors and demountable hollow cathode lamps as energizers.
