Patent number: 9057964Abstract: Imaging optics includes a first mirror in the imaging beam path after the object field, a last mirror in the imaging beam path before the image field, and a fourth to last mirror in the imaging beam path before the image field. In an unfolded imaging beam path between the object plane and the image plane, an impingement point of the chief ray on a used region of each of the plurality of mirrors has a mirror spacing from the image plane. The mirror spacing of the first mirror is greater than the mirror spacing of the last mirror. The mirror spacing of the fourth to last mirror is greater than the mirror spacing of the first mirror. Chief rays that emanate from points of the object field that are spaced apart from another have a mutually diverging beam course, giving a negative back focus of the entrance pupil.Type: GrantFiled: September 20, 2011Date of Patent: June 16, 2015Assignee: Carl Zeiss SMT GmbHInventors: Hans-Juergen Mann, Johannes Zellner, Aurelian Dodoc, Claus Zahlten, Christoph Menke, Marco Pretorius, Wilhelm Ulrich, Hans-Juergen Rostalski

Patent number: 8500276Abstract: Imaging optics for optical devices, with which reflections of the illumination light, which is guided through the same optical elements as the observation light, are kept from reaching the observation pupil of the imaging beam path. The non-reflective imaging optics include at least two refractive optical elements, which are utilized for illumination as well as observation. The at least two refractive optical elements are designed approximately wedge-shaped and are tilted at a random azimuth angle of at least 5° and/or are positioned off-center in the beam path to block out the single reflections of the illumination, occurring at the optical system surfaces, for the observation. The imaging optics are for optical devices, particularly in ophthalmology thought the invention is applicable to other ophthalmological devices as well as to optical devices outside of this field.Type: GrantFiled: February 10, 2011Date of Patent: August 6, 2013Assignee: Carl Zeiss Meditec AGInventors: Jan Buchheister, Lothar Müller, Marco Pretorius
