Microscope, especially laser scanning microscope with adaptive optical device

Microscope, in particular laser scanning microscope with an adaptive optical device in the microscope beam path, comprising two reflective elements, of which at least one is designed as an adaptive optical element, both of which are aligned with their reflector surface perpendicular to the optical axes of the microscope beam path and a polarizing beam splitter whose splitter layer is at the apex of two orthogonal arms of the microscope beam path or two orthogonal parts of a folded microscope beam path, wherein a first of the adaptive elements is associated with one arm and the other with the second arm and is located in each arm between the beam splitter and the beam splitter reflective adaptive element is a λ / 4 plate, as well a detection device, to which the detection light is directed and which is linked via evaluation and adjusting devices with the adaptive elements.
