Method and microscopy system for recording an image

A method and microscopy system are useful for recording an image of a sample region. A laser beam is directed onto the sample region with interface(s). An objective lens facilitates images the laser beam on a focusing point which lies on the optical axis of the objective lens or an axis parallel thereto, and which lies in a focusing plane. The objective lens and the sample region are displaced with respect to one another in relative fashion along the optical axis of the objective lens to different relative displacement positions. Intensity values of the laser beam are captured for a respective relative displacement position. A respective highest intensity value for a respective displacement position, a curve of the highest intensity values, and a reference relative displacement position from at least one maximum of the curve, are determined. Image(s) of the sample region is/are captured at the reference relative displacement position.

Device for decoupling part of the radiation of an observation beam path of binoculars that is freely selectable at any time

A device for outcoupling a portion of the radiation of an observation beam path of a binocular eyepiece for documentation or co-observation that is freely selectable at any time. For the outcoupling, a rotatable supporting unit, the axis of rotation of which is parallel to the axes of the observation beam paths, is arranged in the housing having the binocular eyepiece. Three optical elements are arranged on this supporting unit such that an outer and the middle optical element and, after rotation of the supporting unit, the middle and the other outer optical element are each located in one of the observation beam paths. Here, the two outer optical elements have a beam-splitting effect and outcouple a portion of the observation radiation into a common documentation beam path.
