PlexBright Magnetic Fiber Stubs

The PlexBright Magnetic Fiber Stub is specially designed for use with the Magnetic Head-Mounted LED or the optical patch cable with a magnetic LC ferrule. The magnetic optical fiber connector relieves the torque on the implant from rotational movements such as spinning and twirling.

Description

The PlexBright Magnetic Fiber Stub is specially designed for use with the magnetic Head-Mounted LED or the optical patch cable with a magnetic LC ferrule. The magnetic optical fiber connector relieves the torque on the implant from rotational movements such as spinning and twirling. Each magnet weighs .07 grams, so that the magnetic connection between the fiber stub and Head-Mounted LED and/or patch cable results in a small increase in weight (.14 grams). Directly coupling the magnetic Head-Mounted LED to the magnetic fiber stub eliminates the need for a patch cable.

Ferrule Tip Options
Magnetic fiber stubs are available with LC ferrules

**If using the magnetic fiber stubs with a patch cable, select the optical patch cable with a magnetic LC ferrule**

Fiber Diameters

These fiber stubs are available in 225/245μm or 110/125 fiber diameter
**Before making a decision regarding the fiber diameter, reference the “Power Output at Tissue Interface Tables” on the Technical Specs tab. These tables provide an expected system output actually experienced by the tissue accounting for the specific wavelength chosen, loss due to patch cable and fiber stub connections, and the fiber stub fiber diameter.**
Lengths
The Fiber Stub Implant length refers to the length of the optical fiber exposed beyond the end of the ferrule (or cannula). PlexBright Fiber Stub Implants are available in a choice of 1, 2, 3, 4, 6, 8, 10 and 12mm lengths, or may be customized to the researcher’s specifications. The Fiber Stub Implants are sold in boxes of five or twenty five stubs.
To best maintain the PlexBright Fiber Stub Implant tip, Plexon recommends regular care and maintenance utilizing the PlexBright Optical Fiber Cleaning Kit. This kit has been designed to safely maintain and extend the life of the exposed optical fiber.
PlexBright Starter Kits offer the initial products to get started. Kits are available in four experimental designs and with either driver (the economical kit with the LD-1 Single Channel LED Driver or the fully functional kit with the 4 Channel Controller with Radiant™ Software).

In addition to the PlexBright Fiber Stub Implants, tip-specific PlexBright Optical Patch Cables, and the PlexBright Optical Fiber Cleaning Kit, the PlexBright Optogenetic Stimulation System offers a complete range of super intensity PlexBright LED Modules – controlled by either the stand-alone PlexBright LD-1 Single Channel LED Driver or the advanced PlexBright 4 Channel Optogenetic Controller running Radiant Software, several PlexBright compatible commutators, and the PlexBright Light Measurement Kit. If your experiments include freely behaving animals, you may also be interested in learning more about the CinePlex® and CineLyzer® Behavioral Research Systems.

Your Plexon Sales Engineer is available to provide additional information and to assist you in determining what products might be the best choice for supporting your research.

Technical Specs

Technical specifications for the Fiber Stub Implants may be found below, followed by a table detailing the light output actually experienced by the tissue during experimentation.

Fiber Stub		 Remarks
Lengths 1, 2, 3, 4, 6, 8, 10 or 12mm 1, 2, 3, 4, 6, 8, 10 or 12mm PlexBright Fiber Stub Implant length is the length of exposed fiber. Lengths listed are standard and available immediately. Custom options may also be available, and accordingly will require additional manufacturing time and cost.
Fiber diameters – 110/125µm, or
– 200/230µm		 -110/125um

– 225/245µm

 The first number represents the core fiber diameter, while the second gives the total fiber diameter including the cladding. The larger fiber may be more advantageous if maximum power delivered to the tissue is especially important, while the smaller diameter fiber may be more appropriate when minimal tissue disturbance is of special concern, and/or when working with smaller animals such as mice.
