ABSTRACT:
The hollow cathode lamp can be used as a light source for the atomic absorption and scintillation spectroscopies. It contains a diffusion-protection cylinder to trap the cathode material by blocking the light emission window from the cathode material; the cylinder encloses the optical path leading from the cathode to the light emission window in a space between the cathode and the light emission window.
