These Cannula Implant Guides are designed to provide guidance and stability for a fiber optic cannula during an implantation procedure. The bottom surface of each implant guide features a roughened surface and circular groove (see image to the right) that increases the surface area available to dental cement and improves adhesion to the specimen. A 1.6 mm long protrusion on the implant guide helps stabilize the guide when implanted. Each implant is constructed using lightweight surgical titanium (≤0.11 g) which can be sterilized prior to use. For convenience, the cannula guides are offered below in packs of one or five.

For best results when implanting a cannula, the OGL and OGF should be used with a cannula holder and stereotaxic guidance equipment. To affix the cannula within the implant guide, first insert the cannula into the receptacle of the implant guide. Then, add a small amount of cement or epoxy to the cannula via the two Ø0.8 mm weep holes (see image above). Finally, attach the cannula ferrule to an XCL (Ø1.25 mm ferrule) or XCF (Ø2.5 mm ferrule) cannula holder (see image above).

The OGL implant guide is compatible with our standard Ø1.25 mm cannulae (ceramic and stainless steel) and the OGF implant guide is compatible with our standard Ø2.5 mm cannulae (ceramic and stainless steel). When assembled, the effective length of the protruding fiber is reduced by 1 mm (Item # OGL) or 2 mm (Item # OGF); therefore, these implant guides cannot be used with our 2 mm long cannulae. Additionally, due to the fiber separation distance, the implant guides cannot be used with our dual-core cannulae.

Can you please provide clear instruction on how OGL should be attached to a mouse skull using dental cement? Images of the preparation would be helpful.

The OGL and OGF cannula implant guides could be quite useful for me but they are fairly prohibitively expensive. I make my own fiber optic cannula using thorlabs materials because I can make a good cannula for 5 dollars instead of buying one for 60+ dollars. I need a good means of securing ceramic ferrules to the head, but I really can't be spending 15 dollars per ferrule on the implant. If you had a more affordable option, I would be all over it. Or if you have suggestions for making my own that would be very useful. For example, with metal guides, I can soulder a bit of thin wire to the cannula to make it "grip" the dental cement better. Thanks!

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.

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.

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%.
