Design and Preparation of Quarter-Wave Plate Coatings,

reportActive / Technical Report | Accession Number: ADA294187 | Open PDF

Abstract:

During non-normal incidence on multilayer reflectors, two polarization components will produce different phase shifts. Because of this, it is possible to use computer optimization to design film systems associated with specific phase differences. The object of this article is to design 90 deg phase films. Their functioning will then approximate quarter wave plates. Compared to traditional wave plates, their special features are that it is possible to use them for any wavelength, and they possess high phase difference precisions and large apertures. Two types of design methods are presented in the article. In conjunction with this, preparation techniques and experimental results are reported. AN
