Fiber Coupled Blue LED for Optogenetics in Freely Moving Mammals


The Prizmatix Optogenetics-LED-Blue module is specially designed to provide high power Blue light (~460nm) to activate Channelrhodopsin (ChR1, ChR2) in optogenetics experiments with freely moving mammals. This LED source provides powerful light irradiance of >380 mW/mm² at fiber implant tip following all fiber-optic connections including Rotary Joint.

Optical power and irradiance data for full Optogenetics system including Optogenetics-LED-Blue, fiber patch cord, Rotary Joint, Dual / Single fiber and fiber optic cannula (implant):

Optical Power from 200μm cannula mW >12
Optical Power from 250μm cannula mW >20
Optical Power from 500μm cannula mW >80
Irradiance from 200μm cannula mW/mm² >380
Prizmatix‘s unique large emitter LEDs enable bilateral stimulation with a single low cost light source and simple one channel rotary joint. Using a simple Y-shaped fiber bundle at the rotary joint will double the amount of light delivered to the brain each branch delivering virtually the same power as a single fiber. This results in significant cost saving in setting up bilateral brain activation and silencing systems, compared to alternative light sources.

 Optional Accessories for Optogenetics Experiments

Optogenetics Rotary Joint

Prizmatix Rotary Joint is especially designed for Optogenetics experiments with High NA fibers equipped with FC connectors. Rotary Joint very low friction and smooth swivel operation are demonstrated in this video - showing continuous rotation for over 30 seconds after a fingertip startup. The torque required for free movement is very low thus reducing the Rotary Joint's behavioral effect on freely moving animals.
Prizmatix Rotary Joint can be used with large core input optical fiber connected to several thin output fibers simultaneously. This allows concurrent delivery of light to separate areas of the brain without loss of power due to the fiber split.

Optogenetics Implantable Cannulae

Prizmatix Implantable Fiberoptic Cannulae / Ferrules allow direct light stimulation of certain deep brain regions in living animals. Each Cannula consists of a Zirconia ferrule accommodating a high NA Silica optical fiber, protruding from the Zirconia ferrule at a desired length.

Single/Dual Fibre

Prizmatix provides a full solution to the optogenetics in vivo and in vitro fiber optics. Made of silica or polymer fibers, the high NA fibers are assembled to fit any research set-up with various combinations of connectors, ferrules, core diameters and lengths. Some examples are Y-shaped fibers for simultaneous in-vivo stimulation of two hemispheres, and fibers with stainless steel tip with protruding bare fibers for in-vitro activation of brain slices under a microscope.

Fiber Patch Cords

Prizmatix offers a wide range of standard and customized multi-mode silica / polymer fibers as well as ferrules for optogenetics research. A Y-shaped fiber bundle is especially useful for activating two brain hemispheres simultaneously: a 1000μm or 1500μm fiber is coupled to the LED and connected to one side of the Rotary Joint. From the Joint’s other side emerge two thin fibers which can then be connected to two separate ferrules: the light from the LED is divided equally between the two hemispheres without any loss of power.


The Pulser USB to TTL interface box with user friendly software is an easy way to generate trains of pulses for Optogenetics activation directly from your computer. See more..
