Patent ID: 7986456

Claim:
A scanner arrangement, in particular a scanning microscope, for optically scanning an object in a sequence of scanning steps, comprising: a driveable moving object stage arranged for positioning the object thereon and moving the object, a carriage drive, and an objective assembly having an objective lens carriage, and a front objective lens on the objective lens carriage which is arranged to be moved parallel to a movement direction of the object stage by the carriage drive; wherein the object stage is configured to be driven during the sequence of scanning steps in order to achieve a continuous movement, and the objective lens carriage with the front objective lens is configured to be driven in each of the scanning steps for a forward movement step, in which the front objective lens is moved synchronously with the object stage in the same direction as the object stage out of an initial position, and in each case between successive scanning steps for a backward movement into the initial position, with the object being optically scanned during the continuous movement of the object stage.
