Separate Light Path 2x2 Fiber-optic Rotary Joints connect two arbitrary fiber-optic types on the stationary side of the rotary joint with their respective counterparts on the rotating side. This innovative patent pending technology offers unprecedented possibilities for laser or LED based optogenetics lighting requiring a compact and low loss dual channel fiber-optic rotary joint. This Separate Light Path 2x2 Fiber-optic Rotary Joint makes possible optogenetics and photometry experiments with an independent control of two different sites of illumination and/or detection of the light.

Notes:
• A compatible holder is included with the Separate Light Path 2x2 Fiber-optic Rotary Joints (Holder_FRJ_2x2).
• Two output fiber-optic patch cords are also included.
