Arrangement in the illumination beam path of a laser scanning microscope
View Patent ↗An arrangement in the illumination beam path of a laser scanning microscope, comprising a mirror which can be introduced into the beam path for coupling in at least one additional wavelength, and a method for the operation of a laser scanning microscope with a mirror which can be swiveled in rapidly for coupling at least one additional wavelength into the illumination beam path, wherein the swiveling process is synchronized with the illumination control by a control unit in such a way that at least one additional wavelength is coupled into the illumination beam path when the mirror is swiveled out.
1. A laser scanning microscope having an arrangement in the illumination beam path, the laser scanning microscope comprising a mirror wheel having a plurality of mirrors wherein each of said mirrors can be introduced into the beam path of said microscope for coupling in at least one additional wavelength by means of a light-conducting fiber, at least one area that is transparent to light located on said mirror wheel between said mirrors, and a control unit for synchronizing the introduction of said mirrors into the beam path with an illumination control such that at least one additional wavelength is coupled into illumination beam path when a said mirror is introduced into the beam path.
2. The laser scanning microscope according to claim 1 , wherein an elongated mirror is rotatable around an axis of rotation.
3. The laser scanning microscope according to claim 1 , wherein the mirror is part of an insert in the illumination module.
4. The laser scanning microscope according to claim 1 , wherein an exchangeable interface is positioned in the illumination beam path.
5. A method for the operation of a laser scanning microscope having an arrangement in the illumination beam path with a mirror wheel having a plurality of mirrors which can be introduced into the beam path of said microscope for coupling in at least one additional wavelength by means of a light-conducting fiber, and at least one area that is transparent to light located on said mirror wheel between said mirrors, comprising introducing at least one of said mirrors into said beam path for coupling in at least one additional wavelength, and synchronizing said introducing with illumination control by a control unit in such a way that at least one additional wavelength is coupled into the illumination beam path when the mirror is introduced into said beam path.
6. The method according to claim 5 , wherein the illumination is coupled into the microscope by at least one AOTF whose operation is synchronized with the switching process.
