Scanning immersion microscopy

A method for the microscopy scanning of a specimen. An immersion medium is used between a slide and a microscope objective, said immersion medium wetting a surface of the slide, and the microscope objective being relatively displaced over the surface of the slide for imaging. The surface is provided with a coating which repels the immersion medium.

A microscope comprises a microscope objective, a camera and an imaging optical system for imaging an object through the objective to the camera along a first optical path. A projection optical system is provided for projecting a test image onto the object through the objective, and the imaging optical system is configured to image the projected test image from the object to the camera through the objective and along at least part of the first optical path. A focus adjustment system is provided for focusing the test image at the camera. Using the same objective and the same camera for both imaging and focusing allows reduction of the cost of the microscope in comparison with known microscopes that provide separate focusing systems.

Method for scanning microscopy and scanning microscope

The disclosure relates to a method for scanning microscopy wherein a specimen is scanned simultaneously with a plurality of illumination spots of an excitation light. The light emitted by one specimen location irradiated with one illumination spot is detected independently of the light emitted by another specimen location illuminated with another illumination spot. A microscopic image of the specimen can be compiled from the emitted light detected for the different specimen locations. The method provides that the intensities of the different illumination spots are set independently of one another, and in that the illumination spots are guided over the specimen one after another in a scan line. The disclosure additionally relates to a scanning microscope.
