摘要
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.
