Patent number: 10578881Abstract: An illumination optical unit serves for illuminating objects to be examined by a metrology system. The illumination optical unit has an optical pupil shaping assembly for generating a defined distribution of illumination angles of illumination light over an object field in which an object to be examined can be arranged. An optical field shaping assembly for generating a defined intensity distribution of the illumination light over the object field is disposed downstream of the pupil shaping assembly in the beam path of the illumination light. The field shaping assembly has at least one optical field shaping element arranged in the region of a pupil plane of the illumination optical unit. This results in an illumination optical unit which ensures an illumination which can be set in a defined manner with regard to an intensity distribution and an illumination angle distribution over the entire object field.Type: GrantFiled: December 14, 2018Date of Patent: March 3, 2020Assignees: Carl Zeiss AG, Carl Zeiss SMT GmbHInventors: Thomas Frank, Dirk Doering, Holger Seitz, Mario Laengle, Ulrich Matejka

Patent number: 10322031Abstract: An ophthalmic instrument for the application of laser radiation in a patient's eye, particularly for the examination and/or surgical laser treatment of the cornea and the lens of the eye, includes a femtosecond laser, an objective and optical assemblies. The optical assemblies are arranged in front of the objective, and selectively vary the focus position in the coordinate direction X, Y and Z either within the region of the cornea or within the region of the lens of the eye. The objective or at least one lens group is movable relative to the eye. The variation of the position of the lens group objective shifts the focus position from the cornea to the lens of the eye and vice versa.Type: GrantFiled: May 8, 2018Date of Patent: June 18, 2019Assignee: Carl Zeiss Meditec AGInventors: Mario Sondermann, Marco Hanft, Dirk Doering
