Fiber Coupled Yellow LED for Optogenetics in Freely Moving Mammals
The Prizmatix Optogenetics-LED-Yellow light
source is specially designed to provide Yellow
light (~595nm) for Optogenetics silencing in
freely moving mammals. The Yellow light is
especially fit Halorhodopsin (NpHR, eNpHR3.0)
Yellow light inhibition opsin. This LED light
source provides powerful light irradiance of
>80 mW/mm² at fiber implant tip following all
fiber-optic connections including 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
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. See more..
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. See more...
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.

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.
