Fiber Coupled Orange-Red LED for Optogenetics in Freely Moving Mammals


The Prizmatix Optogenetics LED Orange-Red module is specially designed to provide high power Orange-Red light source (~625nm) to activate or inhibit Red shifted opsins (Jaws, Jaws-ER2) in Optogenetics experiments with freely moving mammals. This LED light source provides powerful light irradiance of >250 mW/mm² at fiber implant tip following all fiber-optic connections including Rotary Joint.

Key Features

  • High Power density (>250 mW/mm²) at fiber's tip following all connections
  • Unique large LED enables bilateral illumination with single LED and rotary joint for significant cost saving and without compromising power at implant tip.
  • Extremely low torque LED-compatible rotary joint suitable for even the smallest animals.
  • Precisely adjustable power by 10 turns potentiometer
  • TTL and Analog Inputs are Opto-Isolated to eliminate ground-loops
  • Analog input (0-5V) for power control
  • USB control (optional)
  • Instant warm up time

Optical power and irradiance data for full Optogenetics system including
Optogenetics-LED-Red, fiber patch cord, Rotary Joint, Dual / Single fiber
and fiber optic cannula (implant):
Optical Power from 200μm cannula mW >8
Optical Power from 250μm cannula mW >12
Optical Power from 500μm cannula mW >50
Irradiance from 200μm cannula mW/mm² >250

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 [2]

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 [3]

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 or Dual Fiber for bilateral activation [4] and Fiber  Patch cords [5]

Prizmatix provides diverse fiber optics solutions for Optogenetics in-vivo. Made of silica, glass or polymer, these high NA fibers can be constructed to fit any research set-up with various combinations of connectors, ferrules, core diameters and lengths. Examples include single stainless steel coverings of bare tipped fibers, or Y-shaped fibers for simultaneous stimulation of two hemispheres.
