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 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.
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.
Optogenetics Pulser is a programmable TTL pulse train generator for pulsing LEDs, lasers and shutters used in Optogenetics activation. The Pulser device comes with user friendly software that enables easy visual setup of numerous pulse train configurations. See Pulser product details
