The invention relates to a device for illuminating organic objects, particular organic objects of the eye. Preferably, the device can be used in an opthalmological diagnosis or therapy device. According to the invention, an array of miniaturized light sources is arranged in a spatially defined manner on a plane or a curved surface such that the light sources achieve a packing density that is as high as possible and can be electronically controlled individually in a very quick manner. The light source array is imaged onto the biological object by means of an optical system.
