The theory is developed for two types of narrow band filters. One is based on the Zeeman splitting of the line absorption coefficient; the other is based on the splitting of the anomalous dispersion curves in a Zeeman multiplet. The latter type filter is very similar to the Lyot-Ohman filter. It uses however the Macaluso Corbino effect instead of the linear birefringence of crystals. It is capable of giving very much narrower transmission profiles than the Lyot-Ohman filter and it has a very wide field.
