  • Unit price per 

Ordering Code:
  • The Assisted 1x2 Fiber-optic & Electric Rotary Joint is an assisted rotary joint that splits a single fiber-optic channel into two, splitting according to intensity (i). They are primarily used for bilateral optogenetic stimulation.  Its rotation is electrically driven as it senses and follows the tethered animal’s rotations. It detects the torsion of the optical cable during animal movement and releases it with a very high sensitivity. The assistance of this rotary joint helps to counter the frictional force of the internal slip-ring and offers quality transmission of electrical signal during any experiment with freely-moving small animals like mice. It comes with 24 electrical contacts.
