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.
