Abstract

A description is given of the Zeeman filter, a very narrow optical bandpass filter. The filtering action is achieved by Zeeman-splitting a resonant absorption line in a magnetic field. With the 2537-Å resonance absorption line of Hg¹⁹⁸, such a filter can produce a filtered line as narrow as 0.005 cm⁻¹.
