Apparatus for damping sound in the optical beam path of a microscope, and microscope having a corresponding apparatus

摘要

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.

主权项

1. An apparatus for damping sound in the optical beam path of a microscope, having an acoustic insulation housing for encapsulating a sound-emitting component, the housing comprising at least one optical entrance/exit opening,
wherein 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, wherein the opening is constituted by a tube extending away from the housing, wherein the tube is equipped with at least one tube branch protruding laterally from the tube, and wherein the tube branch is closed at the end or the tube branch is embodied as a bypass, proceeding from the tube and opening back into the tube or into the housing, having an adapted acoustic wavelength.
