Thorlabs offers Ø1.25 mm and Ø2.5 mm stainless steel or ceramic (zirconia) fiber optic ferrules for constructing pigtailed fiber optic patch cables and assemblies. Ø1.25 mm LC-sized ferrules are compatible with many LC/PC fiber components, as well as our ADAL1 mating sleeve or ADAL3 interconnect. The standard Ø2.5 mm FC ferrule size is compatible with many FC/PC, SC/PC, and ST®*/PC fiber components, as well as our ADAF1 mating sleeve or ADAF2 interconnect. Our ceramic ferrules are also available with a nickel plated brass flange that provides a robust way to interface the ferrule with tubing. Both the bare and flanged ferrules are available with extended lengths, making them useful in optogenetics applications by providing additional clearance when implanted alongside other neural recording devices. Additionally, stainless steel ferrules can be scored to increase the available surface area for the bonding agent, while ceramic ferrules are nonmagnetic, making them ideal for applications sensitive to magnetic fields.
Ferrules are sold in packs of 10 and are available with several different bore diameters for either single mode or multimode fibers, as indicated in the tables below.
Thorlabs also stocks multimode patch cables with polished ferrule ends as well as compatible implantable fiber optic cannulae for optogenetics applications (see the OG Selection Guide tab for available products).

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.
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.

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.
Multilateral 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.
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.
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.

If the intent is for one LED source to connect to seven cannulae for simultaneous light modulation, then a 1-to-7 fiber bundle can be used to split the light from the LED into each respective cannula. 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.
Click on Each Component Below for More Information
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.

These Ø2.5 mm ceramic (zirconia) ferrules have a bore size of Ø126 µm and feature a nickel plated brass flange. They feature a conical tip that allows for APC polishing after fiber installation. Extra material at the tip accounts for height lost when the angle is ground onto the facet, and a large chamfer minimizes the amount of material removed when angle polishing.
The flange provides a simple, robust way to interface the ferrule with tubing. The flange also helps to cement the ferrule in place inside collimation assemblies, making flanged ferrules useful when building fiber pigtail subcomponents for applications such as pigtailed collimators, fiber isolators, and benchtop lasers. The 4-slotted FC-flange on these 2.5 mm ferrules also allows them to be used in tunable FC-connector housings. Additionally, these flanged ferrules feature an extended length, allowing for easy handling and making them useful in optogenetics applications by providing additional clearance when implanted alongside other neural recording devices. These ferrules are compatible with our single mode fibers and APC fiber components, as well as the ADAF1 mating sleeve and ADAF2 interconnect.
