Abstract

A light-scanning microscope including a scan optics for generating a pupil plane conjugate to the pupil plane of the microscope objective, and a variably adjustable beam deflection unit in the conjugate pupil plane. An intermediate image lies between the microscope objective and the scan optics. The scan optics image a second intermediate image (Zb2) into the first intermediate image via the beam deflection unit, wherein the second intermediate image is spatially curved. The deflection unit is not arranged in a collimated section of the beam path, but is instead arranged in a convergent section. Then, in terms of the optical properties and quality thereof, the scan optics needs rather to correspond merely to an eyepiece instead of a conventional scanner objective.
