Abstract
A device for reception and transmission of electromagnetic waves in the visible and/or infrared spectral region and/or the UV-region, emitted by a gaeous, liquid or solid material sample, to an analytical unit, preferably for the determination of the temperature of the material sample. The device comprises a heat-resistant sleeve, open at the front end, with a light wave guide coupled to the analytical unit. In order to record the electromagnetic waves of high intensity, the device has a heat-resistant protective element, arranged at the front end region of the sleeve, which conducts electromagnetic waves.
Claims21
A device for reception and transmission of electromagnetic waves in the visible and/or infrared spectral region and/or the UV-region, emitted by a gaseous, liquid or solid material sample (2, 17), to an analytical unit, preferably for the determination of the temperature of the material sample (2, 17), comprising a heat-resistant sleeve (5), open at the front end thereof, a heat-resistant protective element (12) arranged at the front end region of the sleeve (14) and formed from a material conducting the electromagnetic waves as well as a light wave guide (14) transmitting the emitted electromagnetic waves to an analytical unit, characterized in that the protective element (12) can be flushed by a circulation gas, as the sleeve (5), on its outside, is surrounded by an outer sleeve (3) forming a casing, whereby an annular gap (4) passed through by a flushing medium is formed between the sleeve (5) and the outer sleeve (3).
A device for reception and transmission of electromagnetic waves in the visible and/or infrared spectral region and/or the UV-region, emitted by a solid material sample (2, 17), to an analytical unit, preferably for the determination of the temperature of the material sample (2, 17), characterized by a combination of the following features:
- a heat-resistant sleeve (5), open at the front end thereof, in which a light wave guide (14), coupled to an analytical unit, is provided,
- a heat-resistant protective element (12) arranged at the front end region of the sleeve (14), which protective element is formed from a material conducting the electromagnetic waves, and
- an apertured diaphragm (11) which lies between the material sample (2, 17) and the protective element (12).
