The invention relates to an illumination device, in particular for vehicles. The illumination device comprises at least two semiconductor light sources which emit light with different colours, as well as at least one light guide into which the light from the semiconductor light sources is injected, and a light mixer device that is arranged on the entry side of the light guide and has a transparent light-refracting element, by which the spatial distribution of the light from the light sources is mixed so as to generate light that constitutes a colour superposition of the light from the semiconductor light sources. The transparent light-refracting element comprises an end face which forms a light entry face for the light emitted by the semiconductor light sources, the semiconductor light sources being arranged next to one another and in front of the light entry face.

The invention relates to a display device having a fiber-optic plate and a display with an image plane on which the image information of the display is generated, the fiber-optic plate comprising a fiber bundle with a multiplicity of fiber cores extending beside one another, which are enclosed by a cladding material and which transmit light from an entry face of the fiber-optic plate, facing the display, to an exit face of the fiber-optic plate, wherein the entry face of the fiber-optic plate lies further away from the image plane than the lateral dimension of the smallest image information representable by the display.

There are now provided thin-film solar cells and method of making. The devices comprise a low-cost, low thermal stability substrate with a semiconductor body deposited thereon by a deposition gas. The deposited body is treated with a conversion gas to provide a microcrystalline silicon body. The deposition gas and the conversion gas are subjected to a pulsed electromagnetic radiation to effectuate deposition and conversion.

Thin-film solar cells and method of making

The method for coating plural surfaces on multiple sides of a substrate, especially a lens, includes launching microwave outputs into a microwave reactor at respective microwave launch sites; selecting respective microwave outputs to be greater than or equal to thresholds at which corresponding plasmas having a reduced permeability to microwave radiation arise in the microwave reactor; setting distances between the plural surfaces and microwave launch sites greater than microwave penetrations depths in the plasmas; placing respective dielectric tuning elements in microwave fields formed from the microwave outputs at the launch sites; and adapting the shapes of the dielectric tuning elements to the plural surfaces to be coated, so that plasma inhomogeneities are corrected and coatings with a uniformity of &#xb1;1% are formed on the plural surfaces.

An integrated-optical luminescence sensor having an excitation light beam with a first optical axis (k,), a planar waveguide (,), a sample interacting with the evanescent field thereof, and a detection beam path, with a second optical axis, that comes from the waveguide, and/or a coupling-out grating (,) for coupling out the portion of luminescence light guided in the waveguide, wherein the luminescence light to be detected is physically separate from the excitation light.

The invention concerns a plasma CVD system (in particular a plasma pulse CVD system) with an array of microwave antennas. According to the invention, in order to improve the homogeneity of the layer, interference is prevented by controlling adjacent antennas in a chronologically offset manner. To that end, microcapsules are provided within the macrocapsules of the plasma pulse CVD process. Additionally, the uniformity of the layer deposition at the interfaces between adjacent modules can be optimized by radio-frequency excitation by means of suitable electrodes, magnetic fields or the configuration of the gas inlets. The surface coated in an operating cycle can thus be scaled as required.

In order to guarantee that individual elastomeric components used for medicinal or pharmaceutical purposes have improved inertness and static and sliding friction properties, a suitable layer is provided on the elastomeric components for this purpose by the method of the invention. This method includes providing an extended flat mat made of elastomeric material including connected protruding elastomeric components; coating at least one side of the mat including the connected elastomeric components by means of a PECVD or PICVD method to provide a silicon dioxide layer containing carbon, hydrogen and/or nitrogen on the at least one side of the mat; and punching the connected elastomeric components out of the mat to form individual unconnected elastomeric components, each at least partially coated with a portion of the layer.
