Laser microscope

A microscope comprising:

• an inverted microscope stand having a front side and a rear side opposite said front side,
• an objective attached to said microscope stand and defining an optical axis,
• an ocular tube for visual observation arranged at said front side of said microscope stand,
• a reflected light illumination beam path defined by an opening in said microscope stand leading from said rear side of said microscope stand to said optical axis, intersecting said optical axis and comprising at least a tube lens,
• a radiation source at said rear side of said microscope stand for generating an illuminating radiation beam that is harmful to eyes of an observer, said illuminating radiation beam being coupled into said reflected light illumination beam path at said rear side of said microscope stand,
• a mirror for deflecting said illuminating radiation beam in a direction toward said objective,
• a shutter for interrupting and releasing said illuminating radiation beam, said shutter being positioned between said radiation source and said mirror,
• an object stage,
• a radiation screen above said object stage, which radiation screen is arranged to be folded away, and
• a sensor generating a trigger signal coupled to said shutter for triggering said shutter to interrupt said illumination radiation beam when said radiation screen is folded away.

A microscope having a microscope stand, including an optical beam path and an objective arranged along said optical beam path, said objective having a focal plane, said microscope comprising:

• a radiation source for generating an illuminating radiation beam along an illumination beam path,
• a coupling device for coupling said illuminating radiation beam into said optical beam path for illuminating an object,
• a scanning unit for deflecting said illuminating radiation beam into mutually perpendicular directions, said scanning unit being positioned between said radiation source and said coupling device,
• a beam divider positioned between said radiation source and said scanning unit for separating a measuring beam path of radiation leaving an object from said illumination beam path,
• three confocal detection channels each comprising a stop in a plane confocal to said focal plane of said objective and a detector,
• color dividers arranged in said measuring beam path for separating light of said measuring beam path into different ones of said confocal detection channels, and
• reflector slides for receiving said color dividers, said reflector slides having one empty switching position to release said radiation leaving said object completely into one of said three confocal detection channels.
