Abstract
A telescope system (100) comprises a steering minor (M5) arranged in a part of its optical path (L5-L6) between a first telescope stage (10) and a second telescope stage (20). The steering mirror (M5) is configured to controllably rotate over a rotation angle (θm) for controlling a view angle (θv) of the telescope system (100) from the entrance aperture (A1). The steering mirror (M5) is disposed at an intermediate pupil (Pi) of the telescope system (100), at which position an image of the aperture stop (As) is formed by one or more of the optical components (M7,M6) there between.

A telescope system comprising
- an entrance aperture for allowing light to pass into the telescope system at an entrance side of the telescope system;
- an exit aperture for allowing the light to pass out of the telescope system at an exit side of the telescope system;
- optical components configured to shape and guide the light along an optical path inside the telescope system between and through the respective entrance aperture and the exit aperture rtures, wherein a first part of the optical path is determined by a first subset of the optical components forming a first telescope stage of the telescope system, wherein a second part of the optical path is determined by a second subset of the optical components forming a second telescope stage of the telescope system, wherein the telescope system has an aperture stop determined by a minimum opening limiting light passing between and through the entrance and exit apertures of the telescope system via the optical components along the optical path;
- and
- a steering mirror arranged in a part of the optical path between the first telescope stage and the second telescope stage and configured to controllably rotate over a rotation angle for controlling a view angle of the telescope system from the entrance aperture, wherein the steering mirror is disposed at an intermediate pupil of the telescope system, at which position an image of the aperture stop is formed by one or more of the optical components there between.

- and
- a steering mirror arranged in a part of the optical path between the first telescope stage and the second telescope stage and configured to controllably rotate over a rotation angle for controlling a view angle of the telescope system from the entrance aperture, wherein the steering mirror is disposed at an intermediate pupil of the telescope system, at which position an image of the aperture stop is formed by one or more of the optical components there between;
- a back-end optical device comprising an interferometer configured to interferometrically measure light beams traversing the at least one telescope system;
- a reference mass disposed at a virtual entrance pupil of the at least one telescope system;
- and
- a controller configured to control the steering mirror to change the view angle of the at least one telescope system to receive or transmit the light beams to another optical system.
