Abstract
A laser microdissection device includes a microscope stage for carrying a specimen to be cut, a laser light source for generating a laser beam and a microscope objective for focusing the laser beam onto the specimen. An optical laser scanning device is configured to deflect the laser beam so as to move the laser beam focus in an X-Y direction perpendicular to a main axis of the microscope objective. The laser microdissection device also includes at least one of a Z displacement device configured to move the microscope stage in a Z direction, or an optical focus shifting device configured to move the focus of the laser beam in the Z direction. The Z displacement device and/or optical focus shifting device are controllable, together with the optical laser scanning device, so as to move the laser beam focus in the specimen along a three-dimensional cut line in an X-Y-Z direction.
