Abstract
A monolithic corrector plate for an interferometer, includes a substrate having an input face for intercepting a first beam emitted by the interferometer, and an output face opposite the input face. An aperture integral with the substrate is configured to transform a first beam intercepted by the input face into a second beam emerging from the output face.
