1. A microscope having at least one illumination beam path and at least one detection beam path, characterized in that each illumination beam path is provided with a focusing arrangement for producing a linear object illumination region which extends in a direction of an illumination axis of the illumination beam path, a detection direction of the at least one detection beam path is approximately orthogonal to the linear object illumination region, and at least one mobile arrangement is provided for producing a relative movement between the linear object illumination region and an object to be studied, wherein the linear object illumination region is essentially limited to the direction of the illumination axis.
