Abstract
A dual optical path rotary joint provides a low friction coupling of optical fiber connections for optogenetic research and other applications. Two optical paths are provided through the rotary joint which are rotation-insensitive. The ends of the rotary joint rotate with respect to a common housing, which may be provided with ball-bearings or other suitable low-friction rotational mounts in which a first rotating component and a second rotating component are secured. The first and second rotating components are not mechanically linked in rotation, and their rotation is only synchronized by magnets disposed on the first rotating component and the second rotating component. A pair of optical fibers is coupled to the first rotating component and another pair of optical fiber is coupled to the second rotating component. A pair of isolated optical paths links the pairs of fibers, which are directed between the first and second rotating components by reflection.
