Summary: | The invention describes an objective lens switching device (1) comprising a prismatic cuvette (2) perpendicular to a plane parallel to a direction of detection (DD) and a lighting direction (DI) which are mutually perpendicular. The cross-section of the prism is a polygon with more than four sides with pairs of mutually perpendicular faces (2a, 2a'; 2b, 2b'; 2c, 2c'; 2d, 2d'). Furthermore, at least several pairs of faces (2a, 2a'; 2b, 2b'; 2c, 2c'; 2d, 2d') comprise one face (2a', 2b', 2c', 2d') designed to receive a planar light beam (6) in the lighting direction (DI) and one face (2a, 2b, 2c, 2c) with a coupled lens or objective lens (9a, 9b, 9c, 9d) to detect fluorescent light (8) in the direction of detection (DD). The cuvette (2) can rotate about an axis perpendicular to said plane, allowing a specific objective lens (9a, 9b, 9c, 9d) to be oriented in the direction of detection (DD). |
