Abstract

L'invention concerne un dispositif de protection destiné à être employé dans un système de détection d'objets d'intérêt dispersés dans un échantillon, ledit système comportant : - une source (1) de rayonnement lumineux destinée à émettre un rayonnement lumineux (10) suivant une direction principale (X), - un capteur (2) d'image, - une zone de visualisation (Z) transparente destinée à recevoir ledit échantillon et positionnée entre ladite source (1) de rayonnement lumineux et ledit capteur (2), et ledit capteur (2) étant agencé pour acquérir sur sa surface une image de l'échantillon à partir d'un rayonnement transmis à travers la zone de visualisation par ladite source de rayonnement, - ledit dispositif comportant des moyens de protection à intercaler entre la source (1) de rayonnement lumineux et ladite zone de visualisation (Z) pour protéger ladite zone de visualisation du dépôt d'impuretés.The invention relates to a protection device intended to be used in a system for detecting objects of interest dispersed in a sample, said system comprising: - a source (1) of light radiation intended to emit light radiation (10) along a main direction (X), - an image sensor (2), - a transparent viewing area (Z) intended to receive said sample and positioned between said source (1) of light radiation and said sensor (2), and said sensor (2) being arranged to acquire an image of the sample on its surface from radiation transmitted through the viewing area by said radiation source, - said device comprising protection means to be inserted between the source (1) of light radiation and said viewing area (Z) to protect said viewing area from deposition of impurities.
