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. For optogenetics applications, 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. Please note that all of our ferrules have a PC-polished end face, and are not suitable for APC polishes.

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).

what is the material of the ceramic? isSiO2 or Al2O3 or others? may I see the specification of the ceramic?

cdolbashian (posted 2022-07-06 10:50:06.0)

Thank you for reaching out to us with this material inquiry. For all components made, nominally, of a singular material, the material will be listed in the bottom right corner of the mechanical drawing (Auto Cad Pdf), which is located by clicking the "Docs" icon on the overview page. In this case though, the material is Zirconia.

Hello, We currently use your ceramic ferrules CF126-10 and CF128-10, which we have cut at a length of 3mm (from the tip from which the fibers are inserted), because our fibers' coating is stripped over a short distance only. Our problem is that since the fiber is only guided over a short distance, it is not well aligned and may move during manipulations. Therefore, we are looking for a ferrule with a first bore diameter of 128um (that part doesn't change) over a distance close to 2mm, followed by a second bore of 160um (to guide the coated part) over a longer distance (about 8mm would be nice). I've seen that you offer stainless steel ferrules with two different bore diameters, but they do not correspond to our needs. Would it be possible to make a ferrule that matches our needs ? We do not have a material preference. Thank you very much.

Thank you for reaching out to Thorlabs. We are able to provide a degree of customization with our stainless steel ferrules. I have reached out to you directly to discuss this further.

Peter Moselund (posted 2021-08-10 08:16:22.42)

You note the bore size tolerance, but what is the typical concentricity tolerance of your various ferrules?

cdolbashian (posted 2021-08-27 09:41:53.0)

Thank you for contacting us at Thorlabs. The concentricity generally depends on the specific ferrule, and material. Ceramic ferrules tend to have a better concentricity, but without knowing a specific part number we cannot comment on a general concentricity. I have reached out to you directly to inquire about which model, specifically, you are interested in learning about.

Hello, I'm using a multimode fiber (FG105ACA) with core/cladding diameter of 105um/250um, and thinking to connectorize it to the 2.5mm ceramic ferrule. It seems that the item CF128-10 is compatible with the FG105UCA fiber that has the same core/cladding diameter with mine. Could you check if this ferrule works for my fiber? Thank you.

tfrisch (posted 2017-01-26 05:26:50.0)

Hello, thank you for contacting Thorlabs. FG105ACA actually has a cladding diameter of 125um, so the 128um bore of CF128-10 would be best, yes. The coating (250um) should be stripped off prior to connectorization.

Hello, We currently use your stainless steel ferrules (SFLC230-10) and I wanted to offer a suggested variation on it. We find that they are difficult to work with because they are too short. Therefore, we end up glueing two together with a sleeve to double the length. It would be nice if you offered the 1.25 mm ferrules also at a longer length (12 mm). It seems that this would be easy to manufacture and would be very helpful to us and others.

Could thoralbs provide with empty ceramic ferule with 1mm ID and standard 2.5 OD ?

jlow (posted 2014-07-14 11:34:04.0)

Response from Jeremy at Thorlabs: We do not have the ceramic ferrule with 1mm ID. We can provide this with stainless steel ferrule.

RLopes (posted 2014-01-23 18:47:23.77)

We need to machine some features on this part, but have been unable because it is the fired ceramic. Can you supply this part before the ceramic firing process? OR... could you advise on a machining process/tooling requirements so we can machine the part as provided?

jlow (posted 2014-01-29 04:21:17.0)

Response from Jeremy at Thorlabs: We do not supply ceramic before the firing process at the moment. Machining zirconia ceramic would typically require the use of diamond cutting tools.

ma.dmitry (posted 2013-07-02 13:11:04.923)

According to the response on the previous question, Thorlabs can provide stainless steel ferrules with various ID and 2.5 or 1.25 mm OD. But could you manufacture and sell stainless steel ferrules with various OD. I am interested in stainless steel ferrules with OD 750 um (or even less) and ID 250 um. If so, what is the less possible OD?

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.

Multilateral 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.

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.

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.

Cannulae within the same column are interchangeable.

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.

Fiber-Coupled LEDs and Drivers

Our fiber-coupled LEDs are ideal light sources for optogenetics applications. They feature a variety of wavelength choices and a convenient interconnection to optogenetics patch cables. Thorlabs offers fiber-coupled LEDs with nominal wavelengths ranging from 280 nm to 1050 nm. See the table to the right for the LEDs with the most popular wavelengths for optogenetics. A table of compatible LED drivers can be viewed by clicking below.

The preferred power supply (single channel or hub-based) depends on the end user's application and whether you already own compatible power supplies. To that end and in keeping with Thorlabs' green initiative, we do not ship the LEDD1B bundled with a power supply. This avoids the cost and inconvenience of receiving an unwanted single-channel supply if a hub-based system (Item # KCH301 or KCH601) would be more appropriate.
The DC4100 and DC4104 can power and control up to four LEDs simultaneously when used with the DC4100-HUB. The fiber-coupled LEDs on this page all require the DC4100-HUB when used with the DC4100 or DC4104.
These LED drivers have a maximum forward voltage rating of 5 V and can provide a maximum current of 1000 mA. As a result, they cannot be used to drive LEDs which have forward voltage ratings greater than 5 V. LEDs with maximum current ratings higher than 1.0 A can be driven using this driver, but will not reach full power.
The fiber-coupled LEDs sold above are compatible with the LED2 Terminal.
Small Signal Bandwidth: Modulation not exceeding 20% of full scale current. The driver accepts other waveforms, but the maximum frequency will be reduced.
The M565F3 and M595F2 LEDs produce light by stimulating emission from phosphor, which limits their modulation frequency range. These LEDs may not turn off completely when modulated above 10 kHz at duty cycles below 50%.
