Abstract
A device for determining a position and/or an extension of a drop in a position determination space, where the device has a camera having an objective and a beam splitter in the recording area of the camera, and the device is designed in such a way that light coming from the position determination space can enter the objective of the camera along a first light path as well as along a second light path, where light along the first light path can be reflected at a first reflector element in the direction of the beam splitter and can be transmitted through the beam splitter towards the objective, and where light along the second light path can be reflected at a second reflector element in the direction of the beam splitter and can be reflected at the beam splitter towards the objective.
