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: An infrared light source used in spectrometers including an infrared range, a Fourier Transform Infrared Spectroscope (FTIR), etc. The infrared light source is composed of a panel made of sintered silicon nitride plates, a heating element made of metal and embedded in the panel, and a pair of conducting lines for supplying electricity to the heating element. The infrared light is emitted homogeneously from the flat surface of the panel, as compared to a conventional infrared light source using a metal filament in which infrared light is emitted inhomogeneously. It is preferred to form a silicon oxide layer on a surface of the panel to prevent initial change in the infrared emitting characteristic.

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.

Abstract: An infrared source for use in an infrared spectrometer includes an insulator core (19) having a containment cavity, an outlet port in communication with the containment cavity, and an electrically heated infrared element (41) mounted in the containment cavity (38) with a portion thereof facing the outlet port and with the walls of the containment cavity (38) closely spaced to the infrared element. The insulator core is formed of a ceramic fiber material which has excellent resistance to heat and very low thermal conductivity so that very little heat from the infrared element escapes from the insulator core except as infrared radiation through the outlet port. The insulator core is preferably mounted within a central cavity of a metal housing, and may be sealed off from the ambient atmosphere by an infrared transmissive window (24) sealed to an outlet opening in the housing. The electrical supply lines (15) from the infrared element may extend through an opening in the housing which is closed and sealed to inhibit the passage of gases from the ambient atmosphere into the interior of the housing. Where the infrared element is sealed off from the ambient atmosphere in this manner, potentially corrosive gases will be inhibited from reaching the hot infrared element. This containment of the infrared element within the insulator core allows the element to be maintained at a desired temperature for radiating infrared for use in analytical instruments such as infrared spectrometers, while consuming very low amounts of electrical power.
