Abstract:
An inspection apparatus including a light source, a sample holding stage, an image capture device, positioned to receive light from the light source after the light has interacted with a sample on the sample holding stage, and a damage metric. The damage metric includes two or more damage levels, and is a function of light in a test image. Further, the damage metric may correlate to visual observation so that an inspection apparatus may mimic how users of devices will perceive damage to the devices. The damage metric may be adjusted to account for different damage types, for example, abrasion and scratch damage.
Abstract:
Un dispositif d'analyse spectroscopique de carottes de forage (C), notamment de carottes de forage d'exploration pétrolière, minière ou scientifique mettant en œuvre une méthode d'analyse spectroscopique induite par ablation laser (LIBS), comprend un ensemble de mesure (6), avec des moyens optiques d'illumination laser, reliés à une source laser (63), configurés pour diriger au moins un faisceau laser apte à générer en un point de la carotte le plasma requis pour l'utilisation de la méthode LIBS, des moyens optiques de collecte de la lumière du plasma. Une caméra d'imagerie permet de photographier précisément la zone d'analyse et de filmer l'analyse (65). Au moins un spectromètre (93) est relié aux moyens optiques de collecte. Des moyens de traitement de données sont prévus pour traiter les signaux fournis par le(s) spectromètre(s) et les images fournies par la caméra. Un support de carotte (7) supporte la carotte sur une table de mesure, et pour maintenir la carotte dans une position prédéterminée. Des moyens (61, 62) permettent d'opérer un déplacement relatif entre l'ensemble de mesure (6) et le support de carotte (7), selon au moins la direction axiale (A1) de la carotte, et pour positionner le faisceau laser, respectivement l'axe optique des moyens optiques de collecte, en des points prédéterminés de la carotte. Des moyens de réglage (511) facilitent le réglage de la distance entre le support de carotte et l'ensemble de mesure.
Abstract:
A system for inspecting a backside surface of a wafer with multi-channel focus control includes a set of inspection sub-systems including a first inspection sub-system positioned and an additional inspection sub-system. The first and additional inspection sub-systems include an optical assembly, an actuation assembly, where the optical assembly is disposed on the actuation assembly, and a positional sensor configured to sense a position characteristic between a portion of the optical assembly and the backside surface of the wafer. The system also includes a controller configured to acquire one or more wafer profile maps of the backside surface of the wafer and adjust a first focus position of the first inspection sub-system or an additional focus position of the additional inspection sub-system based on the received one or more wafer profile maps.
Abstract:
A threaded connection body (20) is welded to the outer surface of the wall (10) of a pipe, seachest or other flooded cavity (4) within the hull of a ship or floating offshore installation. A sealed cutting apparatus (50) is mounted via a valve unit (30) on the connection body and a cutter extended through the open valve (34) to form an opening (18) in the wall (10). After retracting the cutter and closing the valve (34), the cutting apparatus is replaced by a sealed inspection unit (70) having a camera (71) which is extended through the valve and the opening to inspect the cavity (4). After retracting the camera and closing the valve, the inspection unit is replaced by a plug deployment unit (100) which is used to advance a plug (120) through the open valve and screw it into the connection body (20). The valve unit (30) can then be removed and replaced with a cap (90) so that the plug and the cap provide a double seal to the connection body.
Abstract:
Metrology tool stage configurations and respective methods are provided, which comprise a pivoted connection arranged to receive a wafer and enable rotation thereof about a pivot; a radial axis arranged to move radially the rotatable pivot connection attached thereto; and optics having a stationary part configured to generate a collimated illumination beam. For example, the optics may be stationary and the radial axis may be centrally rotated to enable stage operation without requiring additional space for guiding systems. In another example, a part of the optics may be rotatable, when configured to receive illumination via a mechanical decoupled or empty region, receive power and control wirelessly and deliver data wirelessly. The disclosed configurations provide more compact and more robust stages which efficiently handle large wafers. Stage configurations may be horizontal or vertical, the latter further minimizing the tool's footprint.

Verfahren und Mikroskop zur SPIM Mikroskopie, wobei in einem ersten Schritt anhand einer zu untersuchenden Probe eine Kalibrierung erfolgt indem in unterschiedlichen Probenebenen die tatsächliche Lage des Lichblattes in Anhängigkeit von der Lage in der Probe erfasst und abgespeichert wird, und die abgespeicherte Lage des Lichtblattes in einem zweiten Schritt bei der Betrachtung und/oder Detektion des Probe anhand der im ersten Schritt abgespeicherten Werte zur Korrektur der Lage des Lichtblattes zur Fokusebene des Detektionsobjektives herangezogen wird, und/oder während der Verschiebung der Probe eine Justierung der Lage des Lichtblattes zur Fokusebene des Detektionsobjektives dergestalt erfolgt, dass das Lichtblatt eine Relativbewegung in mindestens einer Richtung zur Probe und/ oder das Detektionsobjektiv eine Relativbewegung zur Probe ausführt.
Abstract:
The present disclosure is directed to a liquid measuring system for producing one or more property values of a liquid. The system can comprise: a thin film device and one or more measuring devices for measuring said one or more property values. This disclosure is particularly directed to a system comprise a thin film device for producing a thin film of the liquid on a spinning disk. The system is particularly useful for measuring color and appearance properties of the liquid. The system can be useful for producing coating compositions.
