Abstract:
1. An optical system, comprising: a primary mirror having a central axis, configured to reflect light incident thereupon; a secondary mirror facing the primary mirror, configured to receive the light reflected from the primary mirror and redirect the light reflected from the primary mirror in a plurality of light channels, the secondary mirror having a tilt and decenter, such that an optical axis of the secondary mirror forms an angle with the central axis of the primary mirror to define the secondary mirror tilt, and such that a vertex of the secondary mirror is displaced from the central axis of the primary mirror to define the decenter; and at least two tertiary mirror elements, each sharing a common tertiary mirror prescription but having a respective tertiary mirror element tilt and decenter associated with one of the plurality of light channels, each configured to reflect associated light channels to an associated focal point for each of the plurality of light channels, wherein each of the tertiary mirror element tilts and decenters is such that an optical axis of the at least two tertiary mirror elements form an angle with the optical axis of the secondary mirror to define the respective tertiary mirror title and decenter such that a respective vertex of the respective ones of at least two tertiary mirror elements is displaced from the optical axis of the secondary mirror to define the respective tertiary decenter.
