Paper Abstract

It is shown that a simple achromatic polarization-preserving beam displacer can be realized in the Porro's two-prism image erector system. The theory of geometric phase and compensating phase shifting is used to illustrate the mechanism of achromatic property in the system. Tilting tolerance and the influence of material, such as CaF2 and plactic materials, are also addressed. The tilting errors of each component or totally internal reflected surface will not seriously affect the performance.
