Abstract:
Luminometer comprising a chassis protected by a cover whose interior is accessible past a closure flap, a detector for measuring photons with a measuring window, a platform supporting specimen plates, an electronic module for amplification and digitizing data and an electronic module for processing these data, wherein the measuring detector is movable and said luminometer comprises motor means for displacing said detector at least along the Z axis,wherein the chassis is provided with means for displacement in translation only along one of the axes of the plane, the axis Y, and the detector and the means for displacement in translation along the Z axis are carried by a means for displacement in translation along the other of the axes of the plane, the axis X, and wherein the means for displacement in the Z direction comprises a carriage mounted slidably on a rail oriented along the axis Z and a motor with an integrated encoder secured t o a frame, driving a cam in rotation provide d to ensure said displacement in translation, this frame being carried by a carriage mounted slidably on a rail, supported by a beam mounted at one of its ends, oriented along the X axis, said carriage being driven by an assembly of a belt stretched between a roller and a pulley of a motor with an integrated encoder.
