Paper Abstract

The Amici roof prisms are used in optical instrumentation as beam deviators and erecting image devices. These prisms are right angle prisms are right angle prisms with a roof in place of the reflecting hypotenuse plane (see fig. 1). The roof gives to the prisms its main properties. All the rays entering to an Amici prism carry out two total internal reflections, each reflection on each face of the roof. Some of these rays incide by first time on the upper face of the roof and leaves the prism after reflecting on the lower face; the other rays reflects in reversed order. We will call type one rays to the first ones, and type two rays to the second ones. This difference between the rays causes a division of the field of view, the boundary being a straight line coincident with the edge of the roof. Some authors'2'3) have investigated how the images are affected when the prism is used with polarized light and how to improve the performance of the prism. As far as we know, nobody has used these prisms as polarizing elements in an optical instrument or setup. In this work we analyze the polarizing properties of such prisms and explore their usage as a phase and amplitude edge spatial filter.
