A method and device for geometrically determining features of a workpiece, having an image processing sensor having a first beam path, the first beam path comprising at least one front optical unit facing the workpiece to be measured, and an optical splitter being mounted on the side of the front optical unit facing away from the workpiece. The optical splitter connects a second beam path to the image processing beam path, a common beam path being formed, and the second beam path being associated with a second optical sensor, the image processing sensor and the second sensor being designed to directly measure the surface of the workpiece. The front optical unit is formed as a sphere and/or has a longitudinal chromatic aberration.
