Abstract
In spectroscopy, hollow cathode lamps are subject to increased requirements for radiation parameters. To check spectrometric equipment, it is necessary to create a highly stable source of spectral lines, the intensity of which on the given spectral lines will remain unchanged (≤1%) for a long time. A solution to this problem is proposed, and a scheme of an experimental test bench for a hollow cathode lamp with an optical-electronic negative feedback loop is presented. The feedback signal controls the current source, which is a functional unit of a specialized power supply unit and generates an electric current flowing through the lamp. The results of an experimental study with an appropriate metrological analysis are presented. The proposed technical solution to build a stable source of spectral lines allowed us to obtain a high level of stability of spectral lines in both the short and long term.
