Abstract
(DE)
Die Erfindung betrifft ein ATR-Spektrometer mit einem ATR-Kristall (1), der einen kegelstumpfförmigen Abschnitt (3) und zwei ebene, parallel zueinander angeordnete Oberflächen aufweist, einem Emitter (11), der eingerichtet ist elektromagnetische Strahlung (13) via eine der Oberflächen und im Wesentlichen senkrecht zu der einen Oberfläche auf die Mantelfläche (16) des kegelstumpfförmigen Abschnitts (3) zu emittieren, wobei die Mantelfläche (16) eingerichtet ist die elektromagnetische Strahlung (13) auf die eine Oberfläche zu reflektieren, so dass die Strahlung (13) unter Mehrfachreflektion an den zwei Oberflächen in dem ATR-Kristall (1) ausbreitbar ist und anschließend mittels einer Reflektion an der Mantelfläche (16) des kegelstumpfförmigen Abschnitts (3) aus dem ATR-Kristall (1) auskoppelbar ist, und einem Detektor (12), der eingerichtet ist die ausgekoppelte elektromagnetische Strahlung (13) zu detektieren.
(EN)
The invention relates to an ATR-spectrometer with an ATR-crystal (1), comprising a section (3) in the form of a truncated cone and two flat surfaces arranged parallel to each other, an emitter (11) designed to emit electromagnetic radiation (13) via one of the surfaces and essentially perpendicularly to said one surface onto the envelope surface (16) of the section (3) in the form of a truncated cone, the envelope surface (16) being designed to reflect the electromagnetic radiation (13) onto the one surface such that the radiation (13) is spread over the two surfaces in the ATR-crystal (1) by multiple reflection, and then coupled out of the ATR crystal (1) by means of a reflection on the envelope surface (16) of the section (3) in the form of a truncated cone, and a detector (12) designed to detect the electromagnetic radiation (13) coupled out of the ATR-crystal.

L'invention concerne un spectromètre à réflectance totale atténuée (ATR) comprenant un cristal à réflectance totale atténuée (ATR) (1) qui comprend une partie (3) tronconique et deux surfaces planes parallèles l'une à l'autre, un émetteur (11) qui est conçu pour émettre un rayonnement électromagnétique (13) par le biais de l'une des surfaces et sensiblement perpendiculairement à ladite surface sur la surface d'enveloppe (16) de la partie (3) tronconique, la surface d'enveloppe (16) étant conçue pour réfléchir le rayonnement électromagnétique (13) sur l'une des surfaces, de sorte que le rayonnement (13) puisse être propagé dans le cristal ATR (1) avec réflexions multiples sur les deux surfaces, et ensuite sortir du cristal ATR (1) au moyen d'une réflexion sur la surface d'enveloppe (16) de la partie (3) tronconique, et un détecteur (12) qui est conçu pour détecter le rayonnement électromagnétique (13) extrait.
