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.
