Patent number: 7411201Abstract: A projection objective of a microlithographic projection exposure apparatus has a last optical element on the image side which is plane on the image side and which, together with an image plane of the projection objective, delimits an immersion space in the direction of an optical axis of the projection objective. This immersion space can be filled with an immersion liquid. At least one liquid or solid volume having plane-parallel interfaces can be introduced into the beam path of the projection objective, the optical thickness of the at least one volume being at least substantially equal to the optical thickness of the immersion space. By introducing and removing the volume, it is possible to convert the projection objective from dry operation to immersed operation in a straightforward way, without extensive adjustments to the projection objective or alignment work.Type: GrantFiled: July 28, 2006Date of Patent: August 12, 2008Assignee: Carl Zeiss SMT AGInventors: Hans-Juergen Rostalski, Aurelian Dodoc

Patent number: 7330309Abstract: The contrast of an image produced by epifluorescence microscopy may be increased by placing a high-pass dichroic reflecting film behind the sample. The reflecting film reflects the emission light emitted by the fluorescent tags in the sample back through the objective lens while allowing the shorter wavelength excitation light to pass through the sample holder.Type: GrantFiled: September 13, 2005Date of Patent: February 12, 2008Assignee: Ikonisys, Inc.Inventors: Triantafyllos Tafas, Petros Tsipouras

Patent number: 7310187Abstract: A method of adjusting a projection objective permits the projection objective to be adjusted between an immersion configuration and a dry configuration with few interventions in the system, and therefore to be used optionally as an immersion objective or as a dry objective. The projection objective has a multiplicity of optical elements which are arranged along an optical axis of the projection objective, the optical elements comprising a first group of optical elements following the object plane and a last optical element following the first group, arranged next to the image plane and defining an exit surface of the projection objective which is arranged at a working distance from the image plane. The last optical element is substantially without refracting power and has no curvature or only slight curvature.Type: GrantFiled: April 13, 2007Date of Patent: December 18, 2007Assignee: Carl Zeiss SMT AGInventors: Alexander Epple, Paul Graeupner, Winfried Kaiser, Reiner Garreis, Wilhelm Ulrich

Patent number: 7218457Abstract: Providing an interchangeable lens capable of carrying out quick focus from infinity to a close object with a magnification of almost life size by a light-weight moving lens group, exhibiting excellent imaging performance across an entire focusing range, and obtaining excellent imaging performance by a vibration reduction lens and its drive system appropriately arranged even upon vibration reduction. The lens includes a first group having positive power, a second group having negative power, a third group having positive power, and a fourth group having negative power. The fourth group includes a front group having negative power and a rear group having positive power. When the lens is vibrated, the lens corrects image blur by shifting the front group almost perpendicularly to an optical axis. When focusing from infinity to a close object, the first and the front groups are fixed and at least the third group is moved toward the object side.Type: GrantFiled: September 29, 2005Date of Patent: May 15, 2007Assignee: Nikon CorporationInventor: Takayuki Sensui

Patent number: 7209292Abstract: A method of adjusting a projection objective permits the projection objective to be adjusted between an immersion configuration and a dry configuration. The projection objective includes optical elements arranged along an optical axis thereof, which include a first group of elements following the object plane and a last optical element following the first group, which is arranged near the image plane. The last optical element defines an exit surface of the projection objective, which is arranged at a working distance from the image plane. The last optical element is substantially without refracting power and has no or only slight curvature. The method includes varying the thickness of the last optical element, changing the refractive index of the space between the exit surface and the image plane by introducing or removing an immersion medium, and axially displacing the last optical element to set a working distance.Type: GrantFiled: May 30, 2003Date of Patent: April 24, 2007Assignee: Carl Zeiss SMT AGInventors: Alexander Epple, Paul Graeupner, Winfried Kaiser, Reiner Garreis, Wilhelm Ulrich
