Common Optogenetics-LED Colors:

Opsin Description Product
  Most opsins in optogenetics are activated by blue to red regions of the light spectrum, but some can also use shorter violet light, like around 405 nm. This can be useful in certain experimental configurations. Optogenetics-LED-Violet
ChR2 Channelrhodopsin-2 is a light-sensitive protein that functions as an ion channel. It is one of the most widely used optogenetics opsins for activating neurons with blue light. Optogenetics-LED-Blue
C1V1 C1V1 is an optogenetic tool derived from the algal protein channelrhodopsin-1 (ChR1) and the chloride pump halorhodopsin (HR). It can be used for both excitation and inhibition depending on light wavelength. For inhibition use the green light. Optogenetics-LED-Green
Arch, ArchT Archaerhodopsin is a light-activated outward proton pump. When exposed to green-yellow light, it actively transports protons across the cell membrane, leading to neuronal inhibition (hyperpolarizes the cell). Optogenetics-LED-Lime-Green
NpHR Natronomonas pharaonis Halorhodopsin NpHR is a light-gated inward chloride pump isolated from halobacteria. When exposed to yellow light, halorhodopsin causes hyperpolarization (inhibition) of the cell, effectively suppressing neuronal function. Optogenetics-LED-Yellow
eNpHR3.0 The improved version of NpHR Optogenetics-LED-Orange-RED
ReChR Red-Activatable Channelrhodopsin.
ReChR is useful to activate neurons using red light
ReaChR Red-activatable Channelrhodopsin is useful when deeper tissue penetration is required. The longer wavelength of deep red light has reduced scattering and absorption in tissue. Optogenetics-LED-Deep-RED

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.
See Rotary Joint product details

Rotary Joint


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.
See Optogenetics Implantable Cannulae product details


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.
See Single/Dual Fibre product details

Fiberoptics for Optogenetics


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.


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
