Abstract

A microscope for widefield microscopy having a detection beam path and an illumination beam path. The microscope includes a filter wheel device, which is arranged in the detection beam path and/or illumination beam path and has a filter wheel, wherein the filter wheel is mounted to rotate about an axis, and wherein the filter wheel is divided into segments. Filters forming a first part-circle are arranged in a first part of the segments, such that said filters are consecutively introduced into the detection beam path or illumination beam path when the filter wheel is rotated. A camera records images at a predefined frequency. The filter wheel device includes a motor-driven shaft that rotates the filter wheel at a predefined rotation frequency. The microscope also comprises a control system for synchronizing the image-recording frequency and rotation frequency based on the filters arranged on the filter wheel.
