Teleopto
TELEOPTO
In optogenetics experiment, an optic fiber connected to the head of an animal restricts animal behavior especially in test cages with high walls, gates and other obstacles.Teleopto breaks this wall by enabling complete wireless environment for optogenetic stimulation, using very light receivers sitting perched on animal's head.
Extra small, extra light receivers even suitable for mice.
High brightness LED and optic fiber cannula are coupled to achieve mW order light power at the tip. Colors can be changed just by swapping the LED cannula component.
Remote controller accepts trigger signals from a stimulator, and sends the signals to the receiver. Synchronized light pulses are generated from the tip of the LED cannula (in pulse mode).
Receiver has two types, pulse and continuous, each for high frequency and continuous stimulation. The remote controller is compatible for both receivers, by switching the mode switch. Pulse receiver flashes at the same timing with trigger pulses, whereas continuous receiver alternates on and off upon a new pulse.
Some opsins are activated by blue light and inactivated by yellow light. Together with the 2 channel receiver and two color LED cannula, you can stimulate by two different colors at the same position. The remote controller accepts two independent triggers.
Receiver can be charged and re-used repeatedly by a dedicated charger.
Bilateral stimulation is possible. If you want to stimulate both hemisphere simultaneously please use 1ch receiver. If you want to stimulate each hemisphere one by one, please use 2ch receiver.

STO mk-II is a pulse generator developed for optogenetics.
By connecting the STO mk-II to TRG port on the Teleopto Remote Controller via a trigger cable, you can control the timing of light stimulation by TTL pulses. Pulses are defined by the parameters illustrated below.
Light power meter
model: LPM-100
Specification
| Wavelength | 470nm (blue) 530nm (green) 590nm (Yellow) 630nm (Red) |
|---|---|
| Display | Liquid crystal |
| Resolution | 0.01mW |
| Power | 2x AA batteries |
In optogenetics, it is important to measure the light power at the tip of optic fiber cannula, and the LPM-100 is best suited for this purpose. LPM-100 covers three colors, blue, green and yellow which are commonly used in optogenetics. Easy to use, mobilable by the battery-powered design.
6 channel Hub
model:TeleHub6
By connecting the TeleHub6 to the EXT port on the Teleopto Remote controller, you can use up to 6 infrared emitters at the same time so that you can increase the throughput of your experiment. This device is also useful if you use a maze with many branches or high walls which block infrared signal and prevent a good transmission. By putting several infrared emitters at several positions, it ensures more stable light stimulation.
Note: All infrared emitters send a signal at the same timing.
