A sensor device for detecting an incident energy beam, the sensor device having stacked layers, the layers having: a first photodiode layer, at least four measuring contacts being arranged on electrode layers of the first photodiode layer, at each of which a partial current of a photocurrent dependent on the incident energy beam can be tapped, to determine an x and y coordinate in the three-dimensional coordinate system; and a second photodiode layer fixed to the first photodiode layer, at least four measuring contacts being arranged on electrode layers of the second photodiode layer, at each of which a partial current of a photocurrent dependent on the incident energy beam can be tapped, to determine an x and y coordinate in the three-dimensional coordinate system; wherein at least one of the photodiode layers is transparent.
