Abstract
Transmission curves and theoretical calculi of the magneto-optical filter, designed and built by the authors, are shown together with some observed transmission spectra. At present the filter has a total halfwidth of ≈80mÅ; and the maximum transmission is 25%. From the analysis of the theoretical curves and from the observed spectra, we deduced the possibility of making up a filter with a very narrow passband (less than 30mÅ) and a very high transmission (up to nearly 100% apart from losses arising from the glass cell, lenses and polarizers).
The article concludes with a selection and discussion of photographs obtained with the filter.
