Integrated Design
Our articulated rotary joint patch cables, also known as commutators, are a one-piece solution for optogenetics experiments. The built-in rotary joint interface allows the cable to freely rotate, reducing the risk of damage in optogenetics experiments. Rather than using two fiber patch cables with a separate rotary joint interface, the permanently attached fiber optics directly connect to the light source on one end and the specimen implant on the other. The lens-free design allows the rotary joint to operate over a wide wavelength range.

For a rotary joint interface with removable patch cables, Thorlabs offers the RJ1 1x1 Rotary Joint for FC/PC Multimode Patch Cables. This rotary joint operates over a 400 nm to 700 nm wavelength range, and with FC/PC ports, fibers can be selected with specific cores, NAs, and jacketing types to optimize an experiment.

Rotary Joint Patch Cable 
Mounted Using our C059TC

Rotary Joint
The rotary joint is precision machined and has sealed metal bearings for extremely smooth rotation, long lifetime, and low signal strength variations as the joint rotates. The rotary joint features an external SM05 (0.535"-40) mounting thread for compatibility with our Ø1/2" optic mounts. The Ø0.59" body of the joint can also be quickly mounted using our C059TC clamp, allowing drop-in installation of these cables. See the Mounting Options tab for examples of mounts constructed with Thorlabs' optomechanics equipment.

Fiber Optics
The permanently attached fiber optic leads are designed to provide a complete optogenetics solution for connecting a light source to an implanted fiber optic cannula. They are built with FT200EMT Ø200 µm core or FT400EMT Ø400 µm core, 0.39 NA fiber. 2 m of fiber is on the light source side of the rotary joint, and 1 m is on the specimen side. The fiber on the light source side of the rotary joint includes standard FT020 orange tubing, while the specimen side is protected by either lightweight black tubing, which minimizes cable mass, or stainless steel tubing, which protects the fiber from the specimen. Models are available with Ø1.25 mm or Ø2.5 mm ferrule ends for cannula interconnection. Choose from an FC/PC or SMA connector for compatibility with all of Thorlabs' optogenetics light sources.

Each rotary joint cable includes two protective caps that shield the ferrule ends from dust
and other hazards. Additional CAPF Fiber Caps for FC/PC-terminated and Ø2.5 mm ferrule ends, CAPM Rubber Caps for SMA-terminated ends, and CAPL Fiber Caps for Ø1.25 mm ferrule ends are also sold separately.

Ferrule Size and Fiber Core Size
Our rotary joint patch cables have either a Ø1.25 mm or Ø2.5 mm ceramic ferrule end. Using a lightweight, compact Ø1.25 µm (LC) ferrule minimizes stress on the specimen and offer the ability to implant several cannulae near the same location for applications such as bilateral stimulation. A Ø2.5 mm ferrule end provides easier handling and a more robust connection to the specimen. Smaller fiber core sizes, such as Ø200 µm, are less invasive, making them ideal for smaller specimens. Larger core sizes, such as Ø400 µm, offer a more robust solution for larger specimens, as well as higher power light sources.

Cannula and Component Compatibility
Cannulae and patch cables with different ferrule materials can be mixed and matched without introducing significant additional signal losses. However, fiber core sizes, numerical apertures (NA), and ferrule diameters should match for proper connection and maximum signal strength. Ø1.25 mm ferrules can be connected using an ADAL1 mating sleeve or ADAL3 interconnect, while Ø2.5 mm ferrules use an ADAF1 mating sleeve or ADAF2 interconnect.

Custom Rotary Joint Cables

The fiber leads of these cables are permanently attached to the rotary joint for higher performance and provide a one piece, integrated fiber optic solution. For compatibility with a wide range of cannulae, light sources, and experimental setups, we can produce custom rotary joint cables using fibers with different core sizes and NAs. We can also produce cables with different connectors or any length of fiber on each end of the joint. For best performance, the fiber core size should be 200 µm or greater. We also offer Standard Rotary Joint Cables, with SMA or FC/PC connectors on each end. Contact Tech Support to order a custom rotary joint cable.

Rotary Joint Mounting Options

The rotary joint included in our articulated patch cables features external SM05 (0.535"-40) threading on the non-rotating section. This allows the rotary joint to be mounted into our standard optomechanical hardware and positioned above a specimen enclosure. A selection of example mounts are shown below and to the right, and each can be configured based on enclosure size. Additionally, rotary joints can be custom mounted in enclosure walls or ceilings (bottom right) using either our SM05 tap or by gluing the rotary joint into a ~Ø1/2" hole.

Custom Enclosure Mount

The rotary joint can be mounted in an acrylic sheet (pictured), wood, plastic, or metal enclosure walls and ceilings that have an SM05-threaded (0.535"-40) hole.

Custom holes can be tapped using our 83373 SM05 tap. First, drill or mill out a Ø0.508" hole where the rotary joint is to be mounted. Next, mount the tap in a drill press and manually turn it into the hole to cut threads into the material. To mount the rotary joint, insert the rotary joint's threads into the enclosure wall from the inside.

Alternatively, a ~Ø1/2" hole can be drilled into the enclosure wall, and the rotary joint can be glued into place. Insert the threaded section into the hole from the inside of the enclosure, and do not allow glue to contact the rotating mechanism. We recommend using our G14250 5-minute epoxy.

Hi We've suffered a fibre break near to our rotary; is there any way we can fix this? In particular, information on how to remove the ceramic ferrule from a rotary cable would be very useful. Kind regards Simon
tfrisch  (posted 2017-06-27 03:19:22.0)
Hello, thank you for contacting Thorlabs. Unfortunately, the ferrule is glued in place and cannot be removed for repair. I will reach out to you directly.

Greetings! I would love to be able to purchase JUST the rotary joint from you. I usually work with 300um fiber, and the fiber that connects the rotary joint to the animal needs to be about 0.5m long. I usually order rotary joints from Doric, but if you guys are able to sell them separately, I'd certainly switch. Thanks! Kelly
jlow  (posted 2013-09-18 11:41:00.0)
Response from Jeremy at Thorlabs: The fiber ends are permanently attached to the rotary joint for better performance and to provide a one piece, integrated fiber optic solution. However, we can quote made-to-order rotary joint cables with any length of fiber on each end of the joint, as well as using fibers with different core sizes and NAs. For best performance, the fiber core size should be 200 µm or greater. I will contact you directly to discuss about this.

Optogenetics Selection Guide

Thorlabs offers a wide range of optogenetics components; the compatibility of these products in select standard configurations is discussed in detail here. Please contact Technical Support for assistance with items outside the scope of this guide, including custom fiber components for optogenetics.

 

Single-Site Stimulation

One Light Source to One Cannula Implant

The most straightforward method for in vivo light stimulation of a specimen is to use a single fiber optic with a single LED light source. The single wavelength LED is powered by an LED driver, and then the illumination output is fiber-coupled into a patch cable, which connects to the implanted cannula. See the graphics and expandable compatibility tables below for the necessary patch cables and cannulae to create this setup. To choose the appropriate LED and driver, see below or the full web presentation.

Bilateral Stimulation

The ability to accurately and simultaneously direct light to multiple locations within a specimen is desired for many types of optogenetics experiments. For example, bilateral stimulation techniques typically target neurons in two spatially separated regions in order to induce a desired behavior. In more complex experiments involving the simultaneous inhibition and stimulation of neurons, delivering light of two different monochromatic wavelengths within close proximity enables the user to perform these experiments without implanting multiple cannulae, which can increase stress on the specimen.

Bilateral stimulation can be achieved with several different configurations depending on the application requirements. The sections below illustrate examples of different configurations using Thorlabs' optogenetics products.


Option 1: One Light Source to Two Cannula Implants Using Rotary Joint Splitter

Thorlabs' RJ2 1x2 Rotary Joint Splitter is designed for optogenetics applications and is used to split light from a single input evenly between two outputs. The rotary joint interface allows connected patch cables to freely rotate, reducing the risk of fiber damage caused by a moving specimen. See the graphic and compatibility table below for the necessary cables and cannulae to create this setup. For LEDs and drivers, see below or the full web presentation.

LED DriverFiber-Coupled LEDHybrid Patch Cable1x2 Rotary Joint SplitterOG Patch CableOG Patch CableADAF2 InterconnectADAF2 InterconnectFiber Optic CannulaFiber Optic CannulaFiber Optic Cannula

Option 2: One or Two Light Sources to Two Cannula Implants

If the intent is for one LED source to connect to two cannulae for simultaneous light modulation, then a bifurcated fiber bundle can be used to split the light from the LED into each respective cannula. For dual wavelength stimulation (mixing two wavelengths in a single cannula) or a more controlled split ratio between cannula, one can use a multimode coupler to connect one or two LEDs to the cannulae. If one cable end is left unused, the spare coupler cable end may be terminated by a light trap. See the graphic and compatibility table below for the necessary cables and cannulae to create this setup. For LEDs and drivers, see below or the full web presentation.

Two Light Sources into One Dual-Core Cannula Implant

For bilateral stimulation applications where the two cannulas need to be placed in close proximity (within ~1 mm), Thorlabs offers dual-core patch cables and cannulae that are designed for this specific application. Each core is driven by a separate light source, enabling users to stimulate and/or supress nerve cells in the same region of the specimen. See the graphic and compatibility table below for the necessary cables and cannulae to create this setup. For LEDs and drivers, see below or the full web presentation.
