Abstract:
Apparatus for detecting optical radiation emitted from an array of spots on an object. The apparatus includes a plurality of light guides having respective input ends and output ends, with the input ends ordered in a geometrical arrangement corresponding to the array of the spots. Relay optics collect and focus the optical radiation from the object onto the input ends such that each input end receives the optical radiation from a corresponding one of the spots. Multiple detectors and each coupled to receive the optical radiation from an output end of a respective one of the light guides.
Abstract:
Die Erfindung bezieht sich auf eine Einrichtung zur spektroskopischen Auswertung von Röntgenstrahlung (5) bei der Analyse einer Probe (1). Die Röntgenstrahlung (5) entsteht dabei aus der Wechselwirkung eines Elektronenstrahls (4) mit dem Probenmaterial. Die erfindungsgemäße Einrichtung ist insbesondere geeignet zur Elementanalyse und Elementqualifizierung bei der Materialmikroskopie, z.B. in der Metallurgie und bei der Partikel-Analyse. Erfindungsgemäß umfasst eine solche Einrichtung:- eine lichtmikroskopische Anordnung zur Beobachtung der Probe (1), eine Elektronenquelle (3), von der ein Elektronenstrahl (4) auf einen mittels der lichtmikroskopischen Anordnung ausgewählten Bereich der Probe (1) ausrichtbar ist, und einen Röntgenstrahlen-Detektor (6), ausgebildet zur Detektion der durch die Wechselwirkung des Elektronenstrahls (4) mit dem Probenmaterial entstehenden Röntgenstrahlung (5), wobei Mittel vorgesehen sind, durch die sich der zu analysierende Probenbereich während einer Beobachtungsphase in der Fokusebene eines Objektivs der lichtmikroskopischen Anordnung befindet, und während einer Messphase im Bereich des Elektronenstrahls (4) und im Empfangsbereich des Röntgenstrahlen-Detektors (6) befindet, und eine Abschirmung in Form eines U-förmigen Gehäuses (8) vorhanden ist.
Abstract:
This disclosure relates to a method and apparatus for producing multiple pixel-by-pixel simultaneous and overlapping images of a sample (100) in a microscope (10) with multiple imaging beams (120, 130). A scanning electron microscope, a focused ion-beam microscope (10), or a microscope having both beams (120, 130), also has an optical microscope (140). A region of interest (210) on a sample (100) is scanned by both charged-particle (120) and optical (130) beams, either by moving the sample (100) beneath the beams (120, 130) by use of a mechanical stage (110), or by synchronized scanning of the stationary sample (100) by the imaging beams (120, 130), or by independently scanning the sample (100) with the imaging beams (120, 130) and recording imaging signals so as to form pixel-by-pixel simultaneous and overlapping images.
Abstract:
A fiber optic plate assembly is provided for transferring optical signals to a detector or other optical element within an imaging device or imaging system. The fiber optic plate assembly comprises first and second fiber optic plates coupled via an optical coupling gel configured to permit separation of the two plates from each other to permit repair or replacement of one of the plates. Alternatively, the imaging device may comprise a single fiber optic plate coupled directly to an optical detector.
Abstract:
An electron beam inspecting apparatus is a map projection type and comprises a primary electro-optical system which molds an electron beam emitted from an electron gun into a rectangular form and irradiates the surface of a sample to be inspected with the molded electron beam, a secondary electro-optical system which converges secondary electrons emitted from the sample, a detector which converts the converged secondary electrons into an optical image via a fluorescent plate to focus them to a line sensor, and a controller which controls the charge transfer time to transfer a line image captured by a pixel array provided in the line sensor by interlocking with the transfer speed of stage which moves the sample.
