Method and device for laser cutting microscopic samples

摘要

The invention relates to a method and a device for laser cutting microscopic samples. The device for laser cutting microscopic samples comprises a microscope (1) having at least one lens (6) for observing a sample (12) that is to be cut The lens (6) defines an optical axis (14) and a lens aperture (34). A laser (4) is also connected to the microscope (1). The laser (4) generates a laser beam (41) that is injected into the lens (6) by means of at least one optical system (16). A diaphragm (18) is provided, which generates a dimmed laser beam (4b), whereby the laser aperture (36) generated by the lens (6) is smaller than the lens aperture (34) of the lens (6) itself.
