Abstract:
Die Erfindung betrifft ein miniaturisiertes optisch abbildendes System mit hoher lateraler und axialer Auflösung für endomikroskopische Anwendungen. Die Aufgabe, eine neue Möglichkeit zur Realisierung eines miniaturisierten optischen Kopfes zu finden, die bei hoher lateraler und axialer Ortsauflösung gegenüber üblichen GRIN-Optiken eine deutliche Erhöhung der Photoneneffizienz gestattet, ohne komplizierte mehrlinsige Systeme zu verwenden, wird erfindungsgemäß gelöst, indem eine refraktive plankonvexe homogene optische Linse (22) mit der planen Seite eine ebene Eintrittsfläche (21) des optischen Systems (2) definiert und entlang der dazu orthogonalen optischen Achse (24) der refraktiven Linse (22) nachgeordnet eine erste GRIN-Linse (231) zur Divergenzreduktion des vom Objekt (1) durch die refraktive Linse (22) übertragenen stark divergenten Lichtbündels und eine zweite GRIN-Linse (232) zum Anpassen des von der ersten GRIN-Linse (231) übertragenen Lichtbündels an die Apertur und das Objektfeld des nachfolgenden Übertragungssystems (4) angeordnet sind.
Abstract:
An ultraviolet (UV) radiometer includes as one component a data collection unit (102) which is sufficiently small that it can be placed in UV curing applications which have normally been inaccessible, and as another component, a data reader (101) into which the data collection unit is inserted for displaying and/or processing the actual data collected by the data collection unit during a process run. Because of its small size, the data collection unit makes it possible to obtain true process control in applications that could not previously be monitored. After making a dosage measurement, the data collection unit is inserted into the data reader to display (106) the actual data collected during a UV curing run. After reading the data in the data collection unit, the data reader clears the previously stored data and resets (105) the unit to take a new dosage reading.

A compact, ultra violet light radiation sensing device intended be used by a human being, the device having a casing (1, 14) and including structural elements of: an ultraviolet light radiation sensor (6) with associated microprocessor (7) on a printed circuit board (4), a display (5) on the printed circuit board (4), a battery (10), a piezo-ceramic element (15) to act as a sound causing element upon an electric signal being applied thereto, an insulator (12), and a plurality of contact springs (8; 9; 11) enabling electrical contact from the battery (10) to the printed circuit board (4) and to the piezo-ceramic element (15). The the piezo-ceramic element (15) is upon an impulse force or a tapping applied onto the device casing configured to deliver an electric voltage signal to the microprocessor (7) via the printed circuit board (4) to wake up the microprocessor from a power saving sleep mode and/or for user input to the microprocessor (7) as a function of tapping sequences interpretable by the microprocessor (7).
Abstract:
An optical spectrometer 1 comprises a photodiode 2 and a straining mechanism 4 for imposing adjustable strain on the photodiode. The spectrometer 1 includes measurement apparatus 7 for measuring variation of photocurrent with strain at different values of the adjustable strain imposed by the straining mechanism 4. Adjusting the strain allows adjustment of the band gap E g of the photosensitive region of the photodiode 1, and this determines the cut-off energy for absorption of photons. Measuring variation of photocurrent with strain at different values of the adjustable strain imposed by the straining mechanism allows study of photons within a desired energy range of the band gap energy corresponding to each strain value.
