Abstract: A microscope with a first and a second illumination light beam for illuminating a sample, wherein the first and/or the second illumination light beam evanescently illuminates the sample. For the purpose of CARS testing, the first illumination light beam can be a pump light beam, and the second illumination light beam can be a Stokes light beam. To increase resolution, the first illumination light beam can be an excitation light beam, and the second illumination light beam can be a stimulation light beam.

Abstract: A scanning microscope includes at least one light source, an acousto-optical element, a beam deflection device and a beam guiding device.

The beam deflection device scans the illuminating light beam over or through a sample. The beam guiding device directs the sub-light beam onto the sample.
