1x2 Fiber-optic Rotary Joints - Intensity Division

  • Unit price per 


Ordering Code:
  • This connectorized joint sends the light from an optical fiber on a fixed side into two optical fibers on a rotating side in a 50:50 split. All three connector receptacles are of the FC type. The 50:50 split is essential for bilateral optogenetic stimulation experiments.

    Items includes : 
    Optional items : 
      • Gimbal Holder allows the rotary joint to pivot along two additional axes, further reducing the mechanical stress on the animal.

    Note : In the case of 0.5 NA in output, the rotary joint internally converts NA from 0.22 input to 0.5 output.
