Summary:Device (1) for observing a sample, comprisinga light source (10);an image sensor (35), comprising several pixels (36);a microlens array (30), comprising several convergent microlenses (31), each microlens being disposed facing a pixel, each microlens comprising an image focus, each microlens being configured to form, from light waves being propagated in parallel incidence, a light wave beam (13) converging towards the image focus of said microlens;the device being configured to hold the sample (20) between the light source and the matrix of microlenses;the device being characterized in that it comprises several attenuating elements (32, 32′), each attenuating element being associated with a microlens and with a pixel, each attenuating element being configured to attenuate the light waves converging towards the image focus of the lens with which it is associated.
