摘要：
It is well known that dispersion affects the performance of a wide-band nulling interferometer, since it induces wavelength-dependent phase differences between the arms of the interferometer. This property is used to create achromatic phase shift by combining several dielectric plates. In this paper, we experimentally validate the use of a single glass plate in order to optimize the rejection ratio of a nulling interferometer.
