Assisted 1x1 Fiber-optic & Electric Rotary Joints - 24 contacts

Assisted 1x1 Fiber-optic & Electric Rotary Joints - 24 contacts
  • Unit price per 

Ordering Code:
  • The Assisted Fiber-optic & Electric Rotary Joint 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 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 the electrical signal during any experiment with freely-moving small animals like mice. It comes with 24 electrical channels and one optical channel.

    Notes:

    • The 24-channel Assisted Fiber-optic & Electric Rotary Joints uses the aspheric (AH) lenses with 0.50 NA optimized for reduced optical aberration. It is designed for use at a wavelength of 470 nm but works in the visible range 450-650 nm.

    • The holder for the Assisted Fiber-optic & Electric Rotary Joint is included.

    • The output fiber-optic patch cords are also included.
