A method for production of window elements which can be soldered into a housing in a hermetically tight manner with optical coating and free-form window elements are disclosed. After application of optical coatings, a protective layer is applied to the optical coating, the two layer systems are selectively removed by means of a machining beam of high-energy radiation for the purpose of ablation of a desired optically active free-form surface for window elements with any geometric shape through a localized machining beam in edge regions of the optically active free-form surface such that the protective layer remains on the optical coating as lift-off mask which is lifted off after applying a metallization for a solder layer by an etching process that acts selectively only on the protective layer but not on the optical coating, and the metallization remains only on the peripheral edge regions circumscribing the free-form surfaces.

A device () converts a force or a pressure into an electrical signal and has a first deformation element (), in particular a first membrane (), to apply the force or the pressure to the device () and a second deformation element (), in particular a second membrane (), to convert the deflection of the force or the pressure into an electrical signal. The first deformation element () has a first force transmitter (), and the second deformation element () has a second force transmitter () for transmitting the force from the first deformation element () to the second deformation element (). The first force transmitter () is rigidly connected at its end distant from the first deformation element () to the end of the second force transmitter () distant from the second deformation element (). Both compressive forces and tensile force can be transmitted from the first deformation element () to the second deformation element () by the first and second force transmitters (). A method produces that device.

A measuring cell () for the infrared analysis of fluids, in particular a measuring cell () having a permissible operating pressure of more than 20 bar and preferably more than 50 bar, has a flow channel () for the fluid formed between first and second elements (). Each element is transparent to infrared radiation at least in some sections. The infrared radiation can be radiated into the flow channel () by the first element () and can exit the flow channel () by the second element (). The two elements () are connected to each other in a fluid-tight and mechanically high-strength manner by a connecting layer () arranged between them and made of a glass-containing material, in particular a sintered glass-ceramic material. A measuring system () has that measuring cell (). A method produces that measuring cell ().

The invention relates to a film resistor () comprising a carbon-containing material () into which clusters () of conductive cluster material are introduced, wherein the conductive cluster material has a positive temperature coefficient. The clusters () are surrounded by a graphite casing and embedded in the carbon-containing material (). Furthermore, the cluster material is present in a thermodynamically stable phase. The invention also relates to a method for producing a film resistor (), wherein a PVD process is carried out on a carrier substrate () using a sputtering material under a reactive atmosphere of a carbon-containing gas, and therefore the carbon-containing gas is dissociated and a carbon-containing layer () is deposited on the carrier substrate (), with clusters () of the sputtering material being embedded in said carbon-containing layer, wherein the carbon-containing layer () is heated to a predetermined temperature while the PVD process is carried out, with the sputtering material or a compound of the sputtering material forming in a stable phase at said temperature.

In a method for the production of window elements which can be soldered into a housing in a hermetically tight manner and of a window element sealing a housing, the object of the invention is to achieve an improved hermetic sealing between window and housing through increased adherence and homogeneity in the metal coating and to prevent penetration of scattered light and unwanted radiation. Optically transparent, flat substrate material whose size is sufficient for a plurality of window elements is provided on at least one surface with an optical coating from which frame-like portions on a coated surface which enclose optically active surfaces of the window elements are subsequently removed, whereupon a metal coating that is used for producing a solder connection to the housing is applied to the generated portions having no coating, and the window elements are separated from the substrate material. An optical seal between a soldering layer system, which is associated with the metal coating, and the optical coating prevents penetration of unwanted radiation.

An optoelectronic component that includes a substrate having a first optoelectronic component, a second optoelectronic component arranged next to the first optoelectronic component and a contact point. A support of the substrate includes a second contact point, wherein the second contact point is located opposite to the first contact point and is in electrical connection with the first contact point. An underfiller in a space between the substrate and the support, the underfiller forms a border area between the substrate and the support toward a space free of underfiller, wherein the border area restricts the space free of underfiller of at least one of the first and second optoelectronic components.
