A microscope includes a holder for holding a sample, an objective for imaging at least apart of a sample held by the holder, a detection module, a control unit for setting the focus position of the objective in a first direction for the recording by means of the detection module, and a focusing module for maintaining a set focus position of the objective. The focusing module includes the control unit, a second detector and first focusing optics with adjustable focal length. The focusing module is switchable into a focus-hold mode, wherein an intensity-modulated object is imaged into the sample via the first focusing optics and the objective, and an image of the imaged object is recorded by means of the second detector. The control unit holds the focus position of the objective on the set focus position, based upon the recording of the second detector.
