Patent number: 9335268Abstract: A device (10) and a method for analyzing a sample (16) containing fluorophores use a light source (12) emitting light (?ex) onto the sample (16), and onto a fluorescence standard (14). The fluorophores of the sample (16), given an immission of light of a first wavelength (?ex1), have a first excitation efficiency and, given an immission of light of a second wavelength (?ex2), have a second excitation efficiency. The fluorescence standard (14), given the same immissions of light, has a third excitation efficiency and, a fourth excitation efficiency. An optical element (20) which is arranged between the light source (12) and the sample (16) and/or (12) the fluorescence standard (14) adapts, due to its optical property, a first difference between the first excitation efficiency and the second excitation efficiency and a second difference between the third excitation efficiency and the fourth excitation efficiency to each other.Type: GrantFiled: January 28, 2015Date of Patent: May 10, 2016Assignee: LRE Medical GmbHInventors: Rafael Egger, Jörg Zeiner

Patent number: 8873151Abstract: An illumination system of a microlithographic exposure apparatus comprises a condenser for transforming a pupil plane into a field plane. The condenser has a lens group that contains a plurality of consecutive lenses. These lenses are arranged such that a light bundle focused by the condenser on an on-axis field point converges within each lens of the lens group. At least one lens of the lens group has a concave surface. The illumination system may further comprise a field stop objective that at least partly corrects a residual pupil aberration of the condenser.Type: GrantFiled: April 26, 2006Date of Patent: October 28, 2014Assignee: Carl Zeiss SMT GmbHInventors: Alexander Sohmer, Aurelian Dodoc, Heiko Feldmann, Wilhelm Ulrich, Gerhard Fuerter, Rafael Egger, Artur Moegele, Michael Raum

Patent number: 8334522Abstract: The invention concerns methods and apparatuses for quantitatively determining the concentration of fluorophores of a substance in a sample. A constant portion of the reference light of a reference light wave length (?r) emitted by a reference light source is coupled in by an optical element in the direction of a receiving element. A first value corresponding to the portion of the reference light coupled in which is incident on the receiving element is detected. The sample is irradiated with the excitation light of an excitation wave length (?ex) emitted by an excitation light source. A second value corresponding to the portion of the fluorescent light of an emission wave length (?em) emitted by the sample which is incident on the receiving element. The ratio of the second value to the first value is determined. The number of fluorophores in the substance is determined based on the ratio.Type: GrantFiled: November 12, 2009Date of Patent: December 18, 2012Assignee: LRE Medical GmbHInventor: Rafael Egger

Patent number: 8134687Abstract: An illumination system of a microlithographic exposure apparatus has an optical axis and a beam transforming device. This device includes a first mirror with a first reflective surface having a shape that is defined by rotating a straight line, which is inclined with respect to the optical axis, around the optical axis. The device further includes a second mirror with a second reflective surface having a shape that is defined by rotating a curved line around the optical axis. At least one of the mirrors has a central aperture containing the optical axis.

Publication number: 20100117003Abstract: The invention concerns a method and an apparatus for the quantitative determination of the concentration of fluorophores of at least one substance in a sample. A constant portion of the reference light of a reference light wave length (?r) emitted by a reference light source (28) is coupled in by an optical element (REM) in the direction of a receiving element (38). A first measured value is detected which corresponds to the portion of the reference light coupled in which is incident on the receiving element (38). The sample is irradiated with the excitation light of an excitation wave length (?ex) emitted by an excitation light source (26). A second measured valued is detected which corresponds to the portion of the fluorescent light of an emission wave length (?em) emitted by the sample which is incident on the receiving element (38). The ratio (Emes2/Es2) of the second measured value (Emes2) to the first measured value (Es2) is determined.Type: ApplicationFiled: November 12, 2009Publication date: May 13, 2010Applicant: LRE Medical GmbHInventor: Rafael Egger
