The invention relates to a device (100) for acquisition of biometric features of a face (104) of a person (102), wherein the device (100) is designed for vertical installation for acquisition of the biometric features, wherein the device (100) has a camera (110) for acquisition of the biometric features and a semi-transparent mirror (106), wherein the semi-transparent mirror (106) is arranged between the person (102) and the camera (110) and is oriented such that, on the side of the semi-transparent mirror (106) facing the person (102), the light path of incident light on the semi-transparent mirror (106) is parallel to the light path of the part of this light which is reflected back by the semi-transparent mirror (106), wherein the device (100) further has an operating unit (112) for the person (102), wherein the operating unit (112), together with the camera (110) and a deflection mirror (108) of the device (100), can be adjusted in height by the person (102) in the vertical direction (116), wherein the deflection mirror (108) is arranged on the side of the semi-transparent mirror (106) facing away from the person (102), such that the part of the light transmitted through the semi-transparent mirror (106) and incident on the deflection mirror (108) is deflected into the camera (110) via the deflection mirror (108), wherein the camera (110), the semi-transparent mirror (106) and the deflection mirror (108) have a fixed distance from the operating unit (112) independent of the height adjustability of the operating unit (112). |
