    Abstract: In the procedure, the light beams are incident parallel to the transparent medium and are deflected toward a focal point inside the transparent medium. This avoids the use of refractive lens systems. The focusing lens system according to the invention enables the bundling of light beams of different wavelength to a point inside the sample.This clearly simplifies the design and adjustment of a multicolor fluorescence correlation spectroscopy device.

    Abstract: The invention concerns a device and a method for measuring a sample (2) by correlation spectroscopy. The device comprises a confocal microscope (1) including a focusing optical system (4) whereof the field (7) defines a collecting volume (9). A light source (10) produces an excitation beam (8) which is reflected towards means (11) for directing it on the sample (2) through the microscope. The measuring device also comprises means for detecting (14) the intensity of the light flux (13) produced by the interaction of the excitation beam (8) on the sample and collected by the microscope and means for processing (15) the signal produced by the detection means (14). A photonic structure (24) increasing the collected light flux (13) is arranged at the focal point (7) of the microscope focusing optical system (4) or combined with said focal point (7) by an optical element (29) to form interference bands (25) in the collecting volume (9).

    Abstract: Disclosed in a method and arrangement for performing a spatially resolved non-collinear measurement of the autocorrelation function of the first or higher order by means of a matrix of beam shaping individual elements, such that there is a local splitting of the beam into a beam matrix of conical component beams, where each component beam represents spatially integrated information regarding the partial area of the matrix through which it passes, the interference resolution is thus determined by the matrix geometry, and the interference pattern produced in space by each component beam in a certain plane imaged on a matrix camera supplies an autocorrelation function of the first order or, by utilizing non-linear interactions in a suitable medium, of a higher order accordingly, so that the coherence time or the pulse period of individual laser pulses or trains of multiple laser pulses can be determined as a function of location.

    Abstract: A spectrometer for determining the concentration of a substance within a sample comprises a. a radiation source ( 11 ) for supplying radiation to the sample to be measured; b. a filter ( 15 ) for filtering radiation transmitted by the sample, the filter having a number of pass bands at wavelengths corresponding to absorption peaks in the absorption spectrum of the sample to be detected, the filter being responsive to an applied signal to modulate the wavelengths of the pass bands; and, c. a detector ( 16 ) for detecting the filtered radiation, the detector being responsive to the applied signal to determine the relative intensities of the maxima and minima in the absorption spectra of the substance, characterized in that the radiation source is selectively activated in response to the applied signal.
