Kristof SEIDL has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).
Abstract: An objective is described consisting of a monolithic body of a material at least partly transparent for a part of an electromagnetic spectrum, and whose surfaces include a first optical refractive functional area serving as entrance area through which electromagnetic radiation can enter the objective, a second optical reflective functional area serving as a first mirror, a third optical reflective functional area serving as a second mirror, a fourth optical reflective functional area serving as a third mirror, a fifth optical reflective functional area serving as a fourth mirror, and a sixth optical refractive functional area serving as an exit area through which electromagnetic radiation can exit the objective, wherein the first to sixth optical functional areas are implemented such that a center shading-free, folded optical path extends from the entrance area through the monolithic body via first to fourth mirrors to the exit area, wherein no intermediate image level is located in the same between the entra
