Paper Abstract

We discuss an optical interferometer's beamsplitter from the points of view of visibility loss and phase, critical to astrometry. A beamsplitter having no symmetries is described by 16 parameters, all functions of optical frequency; if all symmetries are present this number is reduced to four, only two of which are relevant to astronomical interferometry. We have developed a novel multi-layer design which covers fully a factor of three in wavelength while contributing a minimum of visibility loss, light loss, and systematic error.
