The Mono Fiber-optic Cannula is an assembly of a bare optical fiber, a fiber ferrule and a receptacle or a sleeve. One side of the ferrule is polished while the implantable part of the fiber protrudes from the opposite end of the ferrule. The ferrule is placed within the receptacle or sleeve to allow connection to the fiber-optic patch cord. The protruding fiber can be implanted into the body while the ferrule or the receptacle is attached to the skin. When the cannula is connected with the patch cord, it is possible to send the light signals to and from the tissue close to the fiber tip. It is imperative for in vivo optogenetics applications that the fiber-optic cannula allows for an efficient, plug and play type connection with the fiber-optic patch cord.

A receptacle is a mechanical holder that defines the positions of the fiber tip and guides the connecting ferrule to the optical coupling position. For Mono Fiber-optic Cannulas we offer zirconia sleeves as the simplest form of a receptacle, M2, M3 and rectangular magnetic receptacles.


Notes:
• The tolerance on the length of the protruding fiber is better than 0.1 mm.
• Sleeves required to connection with a patch cord are ordered separately (SLEEVE).
• Receptacle Adapters are available for M2 and M3 receptacles (FCA).
• A Stereotaxic Cannula Holder is available for implantation to secure the Mono Fiber-optic Cannulas (SCH).
