Abstract:
The invention relates to an optical measurement device for a reaction vessel, and a method therefor. An object is to measure the optical state within a reaction vessel in an efficient, rapid, and highly reliable manner, without an expansion of the device scale. The configuration includes: a vessel group in which two or more reaction vessels are arranged; a light guide stage having two or more linking portions to which front ends of light guide portions, which have a flexibility, that optically connect with the interior of the linked reaction vessels, are provided; a connecting end arranging body that has an arranging surface that arranges and supports along a predetermined path two or more connecting ends, to which back ends of the light guide portions, in which the front ends thereof are provided to the linking portions, are provided, the connecting ends are provided corresponding to the respective linking portions; a measurement device provided approaching or making contact with the arranging surface that has measuring ends that are successively optically connectable with the respective connecting ends along the predetermined path, and in which light from within the reaction vessels is receivable by means of optical connections between the connecting ends and the measuring ends; and a light guide switching mechanism that relatively moves the respective connecting ends arranged on the connecting end arranging body and the respective measuring ends such that they are successively optically connected.
Abstract:
A probe array (1) for an imaging system for examining an object (19) comprising at least one emitter (7) for emitting radiation, a plurality of detectors (9) for detecting radiation and means for directing radiation emitted by the at least one emitter (7) to the object (19) and for directing radiation reflected from the object (19) to at least two of the plurality of detectors (9) wherein in use the emitted radiation is scanned by means (21) across the object (19).
Abstract:
Multiplexer for electromagnetic radiation, e.g. UV-light, in which a single electromagnetic radiation source (203) and a single electromagnetic radiation detector (223) are connectable in turn to a plurality of sample-containing units (207(a)-207(n)). The multiplexer comprises a sled (253) movable in relation to a fixed base (255) by an actuator (281).
Abstract:
L'invention concerne une installation de mesure spectroscopique comportant : - un système de focalisation (2) d'un faisceau laser (3) sur un échantillon à analyser (4), - un système de collection et d'analyse par spectroscopie (17) des rayons lumineux émis par le plasma (15), ce système de collection et d'analyse (17) comportant notamment une fibre optique (18) de collection de la lumière. Selon l'invention, l'installation comporte : - un système motorisé (23) de déplacement de la fibre optique (18), - un système optique d'imagerie (25) du plasma, sous la forme d'image, - et une unité de traitement et de commande (24) comportant : • des moyens pour analyser l'image formée par le système optique d'imagerie afin de sélectionner une zone d'intérêt, • des moyens pour commander le système motorisé (23) afin de placer la fibre optique dans une position permettant de recueillir la lumière provenant de la zone d'intérêt sélectionné du plasma.
