Abstract
A hybrid rotary joint provides both optical and fluid channels for applications such as optogenetic research. The rotary joint has a stationary component and a rotating component. The optical channel and fluid channel permit simultaneous and rotation-insensitive passage of light and fluid from the stationary to the rotating side of the hybrid rotary joint. The input to the optical channel is provided via an input optical fiber and the input to the fluid channel is fluid from a fluid source. The outputs are an optical fiber output and a fluid channel output. As light passes from the stationary side to the rotating side of the hybrid rotary joint, it is deflected off a beam deflector having an angular orientation that is passively aligned and made independent of the angular orientation of the rotating component via the interaction between magnets attached to each of the beam deflector and the stationary component.
