Abstract:
Analyzers and analyzer systems that include an analyzer for determining multiple label species, methods of using the analyzer and analyzer systems to analyze samples, are disclosed herein. The analyzer includes one or more sources of electromagnetic radiation to provide electromagnetic radiation at wavelengths within the excitation bands of one or more fluorophore species to an interrogation space that is translated through the sample to detect the presence or absence of molecules of different target analytes. The analyzer may also include one or more detectors configured to detect electromagnetic radiation emitted from the one or more fluorophore species. The analyzer for determining multiple target molecule species provided herein is useful for diagnostics because the concentration of multiple species of target molecules may be determined in a single sample and with a single system.
Abstract:
A method for measuring a defect on a surface of an object (4501), comprising: directing a first light beam in a first plane of incidence toward a first position on the object (4501); directing a second light beam in a second plane of incidence toward a second position on the object (4501), wherein the angle between the first plane of incidence and the second plane of incidence is zero and wherein the first light beam is directed in a circumferential direction (4504) and the second light beam is directed in a radial direction of said object (4501); detecting a first scattered light beam; and detecting a second scattered light beam; wherein the first scattered light beam comprises scattered light intensity from the first position and the second scattered light beam comprises scattered light intensity from the second position, the method further comprising a step of comparing the first scattered light beam and the second scattered light beam to determine a first aspect ratio of a defect on the surface of the object (4501).
Abstract:
A double-sided optical inspection system is presented which may detect and classify particles, pits and scratches on thin film disks or wafers in a single scan of the surface. In one embodiment, the invention uses a pair of orthogonally oriented laser beams, one in the radial and one in the circumferential direction on both surfaces of the wafer or thin film disk. The scattered light from radial and circumferential beams is separated via their polarization or by the use of a dichroic mirror together with two different laser wavelengths.
Abstract:
A method for detecting an imperfection in a blister package having at least one radiation-transmissible layer (32), optionally moving, the blister package having a flat side and a pocket side, the method comprising the steps of directing radiation (18, 18’) at the flat side and/or the pocket side of the blister package and detecting any radiation (22) emitted from at least one edge of the blister package.
Abstract:
Un dispositif d'éclairage par balayage comporte un centre d'émission à partir duquel un rayonnement est émis dans un secteur d'éclairage 2, une couronne cylindrique 3 (ou une simple portion d'une telle couronne) centrée sur la source et mobile en rotation autour d'un premier axe 4, cette couronne comportant une pluralité de fentes 5 régulièrement réparties autour de son axe de rotation et ayant une même amplitude angulaire α, une portion de cylindre 7 centrée sur la source et mobile en rotation autour d'un second axe 8 croisant le premier axe audit centre en formant un angle non nul, cette portion de cylindre comportant une fente 9 ayant une amplitude angulaire β, un premier dispositif 2 de commande pas à pas de la rotation de la couronne définissant un pas angulaire élémentaire αα tel qu'il existe un entier N1 différent de 1 respectant la condition α=N1.αα, et un dispositif 13 de commande pas à pas de la rotation de la portion de couronne définissant un pas angulaire ββ tel qu'il existe un entier N2 diffèrent de 1 respectant la condition β=N2.ββ. En variante, les parties pleines et vides des éléments 3 et 7 ont des rôles inversés.
Abstract:
A multi-spot scanning technique using a spot array having a predetermined gap between spots can advantageously provide scalability to a large number of spots as well as the elimination of cross-talk between channels. The multi-spot scanning technique can select a number of spots for the spot array (1D or 2D), determine a separation between the spots to minimize crosstalk, and perform a scan on a wafer using the spot array and a full field of view (FOV). Performing the scan includes performing a plurality of scan line cycles, wherein each scan line cycle can fill in gaps left by previous scan line cycles. This 'delay and fill' scan allows large spacing between spots, thereby eliminating cross-talk at the detector plane. In one embodiment, the scan is begun and ended outside a desired scan area on the wafer to ensure full scan coverage.
Abstract:
In einer Vorrichtung insbesondere in einem Mikroskop (10) zur Aufnahme statischer und funktionaler Daten eines Objekts (15) wird ein Modellspeicher (31) zum Ablegen eines erwarteten Modells des Objekts (15) vorgesehen. Zur Visualisierung eines Bildes (35) des Objekts (15) werden Bilddaten des Objekts in einer Sortiereinrichtung (33) in Abhängigkeit von dem gewählten Modell so sortiert, dass ein Bild (35) des Objekts (15) visualisiert werden kann.
