A system for imaging an object is described. The system includes a light source (200) for illuminating the object (210) with light, the light from the light source (200) having a first wavelength. The system further includes an image capturing device (240) and a filter device (220). The filter device (220) is transmissive for light having a wavelength which is different than the first wavelength, and reflective for light having the first wavelength, the image capturing device (240) capturing an image of at least a portion of the object (210) using light transmitted through the filter device (220). The system may further include a dark field illumination system (400) for illuminating the object (210) either simultaneously with the illumination by the first light source (200), or sequentially with respect to the illumination by the first light source (200).

L'invention concerne un système d'imagerie. Le système comprend une source lumineuse (200) pour éclairer un objet (210), la lumière de la source lumineuse (200) possédant une première longueur d'onde. Le système comprend aussi un dispositif de capture d'images (240) et un dispositif de filtrage (220). Le dispositif de filtrage (220) peut transmettre la lumière qui a une longueur d'onde différente de la première et qui réfléchit la lumière ayant la première longueur d'onde. Le dispositif de capture d'images (240) capture une image d'au moins une partie de l'objet (210) en utilisant la lumière transmise depuis le dispositif de filtrage (220). Le système peut comprendre également un système d'éclairage de champ noir (400) pour éclairer l'objet (210) soit simultanément avec l'éclairage par la première source lumineuse (200) soit de façon séquentielle par rapport à l'éclairage au moyen de la première source lumineuse (200).
