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 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 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 work in visible range 450-650 nm.

    • The model with 400 µm core - NA0.57 optical fiber and HDMI electrical connector is specifically designed to use with Twist-on efocus microscope Systems.

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

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