    Fiber photometry experiments detect small power variations from a fluorophore and for that reason the fiber-optic rotary joints within the setup require minimal transmission variation. Because of large core multimode fibers and connector tolerances, transmission variation can only be minimized using a pigtailed version of 1x1 fiber-optic rotary joint. The pigtailed patch cords are made from 0.37 or 0.57 NA, 200 or 400 µm diameter optical fiber with a lightweight metal jacket and FC connectors. The fixed input patch cord measures between 1 and 2 meters in its standard version, while the output rotating patch cord is 0.15 meters long. Different length fiber-optic patch cords can be connected to the output using an FC/FC mating adapter.

    Item includes : 

      • 1 Pigtailed 1x1 Fiber-optic Rotary Joint

    Add optional items : 
      • compatible Holder
      • Gimbal Holder for FRJ: allows pivoting the rotary joint along two additional axes, further reducing the mechanical stress on the animal.
      • FC/FC adapters: used to connect different patch cords to the optical fibers already linked to the rotary joint.
