A computer program for determining the transmission of birefringent filters is described. This program is used for the following investigations: (a) The feasibility of the construction of a birefringent filter that will work simultaneously for wavelengths of 3933.3, 6562.8, and 10830.3 Angstroms. These three wavelengths are of particular importance for solar studies; (b) the off- axis characteristics of Solc filters; (c) the tolerances required for the elements of a Solc filter; (d) the influence of imperfect polarizers on the transmission characteristics of Lyot filters.
