Abstract:
1. A hybrid rotary joint including a liquid connection for coupling to a fluid port of a liquid rotary joint, comprising: a stationary component having a first optical port and a first fluid port; a rotating component having a second optical port and a second fluid port, wherein the rotating component is rotatably coupled to the stationary component, such that the rotating component is rotatable with respect to the stationary component about a rotational axis of the rotating component, wherein light is coupled between the first optical port and the second optical port for all rotations of the rotating component with respect to the stationary component, and wherein a fluid medium is conducted between the first fluid port and the second fluid port for all of the rotations of the rotating component with respect to the stationary component; and a beam deflector for deflecting an optical beam emitted from the first optical port into the hybrid rotary joint into the second optical port along a first central axis of the first optical port, wherein the second optical port has a second central axis perpendicular to the first central axis, and wherein the beam deflector is mounted in a beam deflector housing rotationally coupled to the stationary component such that the optical beam emitted from the first optical port remains incident on a face of the beam deflector independent of the rotation of the rotating component and is directed to provide a deflected beam incident on the second optical port.
