    Abstract: Ein Temperaturstrahler, der eine Wärmestrahlung emittierende Emissionsfläche (19) aufweist, enthält einen Strahlungswandler (14), der mit einem Laserstrahl (13) bestrahlt wird. Der Strahlungswandler (14) weist eine mikrostrukturierte Empfangsfläche (18) und eine mikrostrukturierte Emissionsfläche (19) auf. Diese beiden Flächen sind von einer glatten Umgrenzung umgeben. Die Laserstrahlung (13) wird an der Empfangsfläche (18) absorbiert und in Wärmestrahlung umgesetzt, welche an der Emissionsfläche (19) gleichmäßig verteilt emittiert wird.

    Abstract: A radiation source assembly and transducer incorporating same are suitable for use in measuring spectral absorption properties of a substance to be analyzed, such as a gas. The radiation source assembly has an optical axis. A measuring radiation source provides radiation in the direction of the axis and a reference radiation source provides radiation in the direction of the axis. An optical diffuser is spaced from the radiation sources along the axis. Radiation from the measuring radiation source and radiation from the reference radiation source are applied to the diffuser and the diffuser forms an exiting radiation beam for the assembly from the radiation of the measuring radiation source and reference radiation source. The operation of the radiation source assembly resembles that of a single-path photometer.

    Abstract: The invention is related to an electrically modulatable thermal radiant source with a multilayer structure. The radiant source comprises a substrate (13), a first insulating layer (22) formed onto said substrate (13), a radiant surface layer (11) formed onto said first insulating layer (22), a second insulating layer (24) formed on said radiant surface layer (11), a first metallization (incandescent filament) layer (10) formed on said second insulating layer, a third insulating layer (26) formed on said first metallization layer, and a second metallization layer (15) for contacting formed on said third insulating layer (26). According to the invention, very thin incandescent filaments (10) are formed from said first metallization layer (10) and surrounded by the other elements (22, 11, 24, 26) of the multilayer structure as a uniform, planar plate.

    Abstract: A radiation source assembly for optical transducers used for the analysis of material components of media, whereby the radiation source assembly comprises:

    two thermal radiation sources (1, 2), of which the first radiation source (1) is located, in relation to the second radiation source, in such a position that it emits through the second radiation source (2);
    a band-stop filter (10) located between the first and the second radiation sources, so that the radiation (6) emitted by the first radiation source passes through it. Both thermal radiation sources (1, 2) comprise a substrate (3, 11) made of silicon, of a silicon mixture or of a silicon compound, and a recess (53) made in the substrate, and micro-filaments (4, 5), which are fastened at their ends to the outer surface (51, 52) of the substrate, their radiation (6, 8) emitting regions being at a distance (H) from the bottom surface (54) of the recess. The stop band of the band-stop filter (10) substantially corresponds to the absorption distribution of the material component of the medium to be analyzed with the transducer.
