摘要:
The present invention relates to a housing for radiation-emitting or radiation-receiving optoelectronic components, such as LEDs, and to a method for producing said housing. The housing comprises a composite assembly comprising a base pan (1) and a head pan (5) which are connected by means of a glass layer (2). One section of the top side of the base pan defines a mounting region (12) for an optoelectronic functional element (60) and is additionally a heal sink for the optoelectronic functional element. The head pan extends, at least in sections, over the periphery of the mounting region and forms, above the mounting region, a passage region (52, 61) for the radiation emitted by the optoelectronic functional element or the radiation to be received. When assembling the base part, the glass layer and the head part, the glass layer is heated to such an extent that the glass reaches a viscosity at which the glass adheres, and the base part and the bead part form a composite assembly by means or the first glass layer. Glass makes it possible to produce a hermetic encapsulation with increased thermal stability.

A housing for radiation-emitting or radiation-receiving optoelectronic components such as LEDs and a method for producing the housing are provided. The housing has a base part and a head part that are joined by a glass layer. The top face of the base part defines an assembly region for an optoelectronic functional element and is also a heat sink for the optoelectronic functional element. The head part extends at least in sections over the peripheral extent of the assembly region, and above the assembly region it forms a passage area for the radiation emitted from or to be received by the optoelectronic functional element.

The invention relates to an optical converter system for LEDs, preferably for so-called (W)LEDs, and a method for producing the named optical converter system. The modular-type optical converter system comprises an inorganic converter for converting the radiation emitted from the LED, an inorganic optical component, preferably comprising glass, which is disposed downstream relative to the converter in the direction of emission of the LED, wherein the converter and the first optical component are adjacent to one another and joined at least in sections. The optical converter system possesses a temperature resistance, which lies above that of the system known in the prior art. Also, the preferred components of the system are substantially resistant to UV and to chemicals.

A micropolarimeter comprises an analyzer (1) and a detector (3), which is typically a photodetector array. The detector has a circular configuration of a number N of sectors. Analyzer (1) and detector (3) form a unit with the analyzer assigning different polarization values to the sectors. Analyzer and the detector contain no moving parts. Three different embodiments are proposed for the analyzer: a glass cone, covered with a polarizing thin film stack, a metal grid polarizing array, and an array of polarizing waveguides. The micropolarimeter (14) is used preferably in a microellipsometer system which can serve as a tool for film diagnostics, especially optical characterization of thin films.
摘要:
An X-ray radiolucent material consisting of a beryllium substrate and a protective coating connected to the substrate is produced by applying a protective coating comprised of at least one component selected from the group consisting of silicon oxide, silicon nitride, silicon carbide, and amorphous carbon. Preferably, a CVD process or sputtering is used to apply the protective coating.
摘要:
A sensor head (1) is described, which has a spacer (5b) between a carrier element (2) and the spring arm (7), which, perhaps carries a sensor tip (9) at the free end; the spacer defines the distance d between the spring arm (7) and the carrier element (2). In a preferred embodiment, the spacer (5b) comprises a sacrificial layer (5a), which is etched out, except for the spacer (5b), after the formation of a corresponding layer system between the spring arm (7) and the carrier element (2). The carrier element (2) and the spring arm (7) are each provided with a reflecting layer (4 and 6). In accordance with another specific embodiment, plasmonactive layers can also be provided.
