A device for three-dimensional measurement of an object, with a stereomicroscope of the telescope type, which has a common objective and a first and a second tube lens, a first image sensor, which is assigned to the first tube lens, a second image sensor (8), which is assigned to the second tube lens, and a control unit, which determines the three-dimensional shape of the object from the images obtained with the two image sensors and carries out a predetermined three-dimensional measurement, wherein the stereomicroscope is designed such that the images are obtained with object-side telecentric conditions of the stereomicroscope.
