Abstract: A light source for an atomizing device, specifically an atom absorption spectrometer comprising one, two, or more lamps, whose ray can be selected by means of at least one two-dimensionally moveable optical selection element, and which can be directed in the direction of atomizing device. Fine-tuning is thereby achieved quickly with little constructive expenditure and with low costs. A very high degree of accuracy is possible from the selector through a rotational and highly adjustable rotation spindle.

Abstract: Atom absorption spectroscopy method generates at least one first beam of monochromatic radiation at a certain wavelength. Radiation is separated into a test beam and a reference beam, and only the test beam is led through a test area. Subsequently, both beams pass through a slot system into a monochromator, and after their spectral breakdown, reach a detector system. In order to improve such atom absorption spectroscopy method in a way that allows the test beam and the reference beam as well as their spectra to be guided close to, or adjacent to one other onto the detector system, and, at the same time enables a simple and easy adaptation of the spectrometer's effective spectral range to a monochromator's characteristics, the test beam and the reference beam thus pass through different slots in the slot system and are projected onto essentially spatially separate areas of the detector system, with their spectra's broken-down.

Abstract: An array of photoconductive elements comprises an array of radiation detectors; an electrical lead connected to the array of radiation detectors; at least one amplifier receptive of an output signal of the array of radiation detectors; a summation device receptive of an output signal of the at least one amplifier; and a positive feedback loop for reducing crosstalk by directing an output signal of the summation device to the at least one amplifier. A circuit processes the outputs of the array of radiation detectors. The photoconductive elements may be operated in a constant voltage mode or a constant current mode.
