Optogenetic stimulation with no strings attached
The Teleopto wireless optical stimulation system is the ideal solution for activating opsins in freely behaving mouse or rat. It provides the user with a combination of the typical colours for opsin activation. An Infrared enabled remote controller sends stimulation pulses to a light-weight (1-4g) head-mounted receiver.
The system comprises a selection of fiber optic cannulas. Each cannula connects to a rechargeable battery-containing receiver – removable when not needed. The fiber optic cannula has one or two built-in miniature LEDs, coupled into one or two optical fibers on the other end. These can be inserted into the tissue.
The receiver, which powers up the miniature LED/s in the fiber optic cannula during stimulation, interprets the IR signal from the remote controller. The remote controller should be positioned near the receiver (within 1m, or within 3m if used with an IR emitter – bidirectional). It accepts trigger inputs from an external stimulator source. The frequency of the TTL inputs synchronizes the frequency of the light pulses.
The Teleopto wireless optical stimulation is the perfect equipment for optogenetics manipulation in freely moving animals. If you are also interested in imaging the brain tissue, please have a look at our other solutions, our Pryer Endoscopic Objective and the OASIS Implant by Mightex Systems.
The Teleopto wireless optical stimulation standard set consists of:
- 3 x LED fiber optic cannulas
- 1 x Teleopto receiver
- 1 x remote controller
- 1 x infrared emitter (for increasing the range of the remote controller)
- 1 x Teleopto charger (for charging the battery on the receiver)
- 1 Cannula insertion tool
- 1 dummy receiver (for animal habituation)
- 1 trigger cable (for connection between the remote controller and an external trigger source)
Available cannula options
The default option will be blue/10mm/250um
A thicker fiber means more light will reach the target area if all other variables remain the same, but it is more invasive. As a guideline, the following intensities can be achieved:
The various Teleopto wireless optical stimulation receivers allow the user to select between options of:
- Weight/size/battery life
- Single or two independent channels
- Pulse mode or continuous mode. This affects how the receiver interprets the signal from the remote controller:
The default option for the receiver is 2g and releases a pulsing signal rather than a continuous one.

Frequently Asked Questions
For which animals do you recommend the Teleopto wireless optical stimulation system?
The Teleopto receivers dimensions vary depending on the model you choose. However, with a weight of maximum 3.1g and a size of a penny, the receivers are suitable even for mice!
How can the trigger pulses be generated?
The remote controller accepts TTL trigger signals from a stimulator and send the signals to the receiver. Synchronized light pulses are generated from the tip of the LED cannula. If you don’t own a stimulator, we can provide you with a pulse generator specifically developed for optogenetics.
What is the difference between the 2 colour LED cannula and the bilateral LED cannula? Can I stimulate with more than 2 channels at the same time?
Together with the 2-channel receiver, the 2 colour LED cannula allows stimulation by two different colours at the same position.
The bilateral LED cannula allows stimulation in 2 different locations. If coupled with a single channel receiver, it will stimulate both positions simultaneously. If coupled with a 2-channel receiver, it will stimulate both positions independently.
We have a Teleopto wireless optical stimulation system to control up to 4 channels. Please get in touch for more information!
