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.

Method and microscopy system for recording an image

A method is useful for recording a microscopic fluorescence image of a sample region. An objective directs a laser beam on the sample region having boundary surface(s). A relative distance between the objective and the sample region is altered along an optical axis of the objective to effectuate respective, different relative distances. A respective set of pixel intensity values are effectuated on sensor pixels of an image sensor by the laser beam and transmitted back through the objective is captured for a respective relative distance. A respective focus metric is determined for a respective relative distance based on the respective set of pixel intensity values captured for the respective relative distance. A preferred relative distance is determined based on the determined focus metrics. The preferred relative distance is set, the sample region is illuminated with excitation radiation and the microscopic fluorescence image is captured via the image sensor.

Method and microscopy system for recording a microscopic fluorescence image of a sample region containing a biological sample

A method is used for acquiring and displaying an immunofluorescence image of a biological sample. During a first operating state, the sample is continuously illuminated using the excitation radiation. A relative position between the sample and an optical system, which guides the fluorescent radiation to an image sensor, is changed in dependence on a movement gesture of a user, and a corresponding digital image is displayed. Upon detection of a termination of the movement gesture, a change is made from the first operating state to a second operating state. In the second operating state, the sample is firstly illuminated using the excitation radiation to excite the fluorescent radiation of the fluorescent pigment. An acquisition of fluorescent radiation emitted by the sample then takes place and a corresponding, further digital image is generated. In the second operating state, the acquisition of the emitted fluorescent radiation and the illumination of the sample are terminated after lapse of the second acquisition duration.
