Abstract

The adjuster also can regulate the direction of polarisation at right angles to each other for max. and min. light penetration. Both filters are composed of equally wide, parallel fields (5,6) with alternating polarisation directions, and at least one (7) of them is arranged displaceably in the filter plane at right-angles to the longitudinal direction of the fields (5,6) to an extent equal to the width of the fields.
