Abstract
(DE)
Die vorliegende Erfindung betrifft eine Raman—Mikrospektrometer-Anordnung (100) umfassend eine Auflichteinrichtung (10), welche dazu ausgebildet ist, in aufrechtstehender Konfiguration oder in inverser Konfiguration im Betrieb der Raman—Mikrospektrometer-Anordnung verwendet zu werden und während einer Messung der Raman—Mikrospektrometer- Anordnung zwischen der aufrechtstehenden Konfiguration und der inversen Konfiguration umgeschaltet zu werden; und eine Gitterkomponenteneinrichtung (20), welche planare digitale Strukturen aufweist und welche dazu ausgebildet ist, als eine abbildende optische Komponente und/oder als eine dispergierende optische Komponente im Betrieb der Raman— Mikrospektrometer-Anordnung verwendet zu werden.
(EN)
The invention relates to a Raman microspectrometer assembly (100) comprising an incident light device (10) which is designed to be used in an upright configuration or in an inverse configuration while operating the Raman microspectrometer assembly and to be switched between the upright configuration and the inverse configuration while taking measurements using the Raman microspectrometer assembly. The Raman microspectrometer assembly also comprises a grid component device (20) which has planar digital structures and is designed to be used as an imaging optical component and/or as a dispersing optical component during the operation of the Raman microspectrometer assembly.
(FR)
La présente invention concerne un dispositif à microspectromètre Raman (100) comprenant un dispositif d'éclairage incident (10) conçu pour être utilisé en configuration verticale ou en configuration inverse lorsque le dispositif à microspectromètre Raman fonctionne et pour être commuté, pendant une mesure du dispositif à microspectromètre Raman, entre la configuration verticale et la configuration inverse ; et un dispositif à composantes de grille (20) qui présente des structures numériques planes et qui est conçu pour être utilisé comme composant optique d’imagerie et/ou comme composant optique de dispersion lorsque le dispositif à microspectromètre Raman fonctionne.
