Object illumination device for confocal fluorescence microscopy, has switchable beam splitter for passing emitted light to detector

摘要

The object (1) is excited into emission, and emitted light (13) reaches a detector (15) via a main beam splitter (9) and a detection beam path (16). The main beam splitter is a switchable beam splitter, preferably an acousto-optical beam splitter. The stimulation light is within the fluorescence spectrum.
