Abstract: A light sheet microscope includes: a detection objective configured to image a target region of a sample located in a focal plane of the detection objective; an illumination objective configured to focus an illumination light beam in the sample, the detection objective and the illumination objective being opposite to one another, and the optical axis of the detection objective and the optical axis of the illumination objective being parallel to one another; a first light deflection device having at least one first deflection surface and one second deflection surface, which are each arranged offset to the optical axis of the detection objective and are configured to deflect the illumination light beam focused by the illumination objective in a direction perpendicular to the optical axis of the detection objective such that a deflected illumination light beam forms a light-sheet-like illumination light distribution focused in the focal plane.

Abstract: An apparatus for damping sound in the optical beam path of a microscope, having an acoustic insulation housing for encapsulating a sound-emitting component, preferably a rapidly moving or oscillating beam deflection means, in particular a resonantly oscillating mirror, the housing comprising at least one optical entrance/exit opening, is characterized in that the housing, preferably the opening of the housing, is embodied and/or configured in such a way that the sound otherwise emerging from the housing is largely extinguished by destructive interference without thereby influencing the optical beam. A microscope having a corresponding apparatus is furthermore claimed.
