The present disclosure relates to a devicefor contactless acquisition of biometric data from skin areas. For example, a sensor optics arrangementof the image acquisition unitor an emitter optics arrangementof the illumination unitis offset such that the focal planesof the image acquisition unitand the illumination unitessentially completely overlap. As a result, for example, the area of the optical sensorof the image acquisition unitor the area of the light emitterof the illumination unitcan be used to the maximum, thereby resulting in a significantly improved quality of the acquisition of the biometric features of a hand, in particular the fingers. In addition, the compactness of the devicecan be further increased, for example by beam folding using reflective optical elements
