Abstract:
The present invention relates to methods and systems for performing sample assays, and for producing and measuring optical responses and signatures. According to various embodiments, a system is provided that includes one or more LED (111), a temperature sensor (118), and a temperature regulator (122). The temperature sensor can be in thermal contact with the LED (111), can be capable of measuring an operating temperature, and can be capable of generating an operating temperature signal. The temperature regulator can be capable of receiving an operating temperature signal of the LED and regulating the operating temperature based on the operating temperature signal. According to various embodiments, a method for illuminating a reaction region (108) with excitation beams is provided. The method can include providing a system (100) that includes an LED (111) and a reaction region (108). The method can include generating excitation beams with LED; directing the excitation beams toward the reaction region measuring an operating temperature of the LED; and regulating the operating temperature by transferring heat away from and/or into the LED, based on the measured operating temperature. The reaction region includes a sample.
Abstract:
Vorrichtung zum Erfassen und Erkennen von Objekten (5) eines Materialstromes, umfassend mindestens eine Kamera (1), welche Bilddaten der Objekte an eine Auswerteeinrichtung zwecks Ermittlung von Eigenschaften der Objekte (5) des Materialstromes wie Materialzusammensetzung, Farbe, Größe oder dergleichen übermittelt, sowie eine beliebige Anzahl vorzugsweise reihenförmig angeordneter Leucht-Dioden (4), welche einer Beleuchtung des Materialstromes dienen, wobei der Materialstrom mittels eines Förderelementes (3) transportiert und an einem Erfassungsbereich (12) der Kamera(s) vorbeigeführt wird und wobei zwischen den Leucht-Dioden (4) und dem vorzugsweise am Förderelement (3) lokalisierten Erfassungsbereich (12) eine optische Einrichtung (6) angeordnet ist, welche eine Diffusion des von den Leucht-Dioden (4) emittierten Lichtes bewirkt. Um eine möglichst gleichmäßige Beleuchtung des am Förderelement (3) lokalisierten Kamera-Erfassungsbereichs (12) zu ermöglichen und dadurch Fehldetektionen zu vermindern, ist es erfindungsgemäß vorgesehen, dass die optische Einrichtung (6) mindestens einen auf seinen Innenseiten (14c) verspiegelten Reflexionskanal (14) umfasst.
Abstract:
A capillary flowcell (12) includes an optical axis, the optical axis being defined by, in sequential order, (a) a first (entrance) aperture (14), (b) a first lens (26), (c) a capillary tube (16) having its long axis centered across the optical axis, and (d) a second lens (28). The first lens (26) focuses electromagnetic radiation from the entrance aperture (14), passes through the inner diameter of capillary tube (16) thus maximizing the signal generated by the analyte within the capillary tube (16). The second lens (28) focuses electromagnetic radiation which has passed through the capillary tube (16).
Abstract:
Apparatus and a method for performing high resolution optical imaging in the near infrared of internal features of semiconductor wafers (110) uses an optical device (112) made from a material having a high index of refraction and held in very close proximity to the wafer (110). The optical device (112) may either be a prism (130) or a plano-convex lens (112). The plano-convex lens (112) may be held in contact with the wafer (110) or separated from the wafer via an air bearing (112') or an optical coupling fluid (214) to allow the sample to be navigated beneath the lens (112). The lens (112) may be used in a number of optical instruments such as a bright field microscope, a Schlieren microscope, a dark field microscope, a Linnik interferometer, a Raman spectroscope and an absorption spectroscope.

Abstract:
링모양으로 배열된 광원을 갖춘 링 광 조명기가 개시된다. 각 광원에 대해, 채광기(light collector), 광원으로부터의 광에 대한 균질화 수단(homogenizing means), 및 균질화 수단의 출력을 피조명 영역 내로 영상화(imaging)하기 위한 영상화 수단을 포함하는 빔 성형기가 대응한다. 실시예들의 균질화 수단은 막대(rod)이며, 이 막대 내로 채광기로부터의 광이 지향된다. 채광기 반대편의 막대의 단부(end)는 영상화 수단에 의해 피조명 영역 내로 영상화된다.
