15mm Fiber Mounted LEDs

Deliver optogenetic stimulation from directly inside a Halo microdrive.

Miniaturized LED light source and fiber waveguide module integrated into a single Halo-5 or Halo-10-Mini Microdrive shuttle to deliver optogenetic stimulation from directly inside the microdrive.

Simplified optical assembly increases stimulus consistency and consistent light delivery: no optical connections, patch cords, ferrules or FORJ.

LED drive current is delivered through the tether-headstage-EIB differential stimulus channels

FLED Driver with Pulse 2.0 software is required for use.

  • 4 color options: blue, amber, red and green

  • Integrated into microdrive shuttle - depth adjustment process identical to tetrodes

  • Mount up to 3 modules in 1 microdrive - same color or combine to mix colors

  • Integrates optogenetic stimulation into existing Neuralynx systems, including wireless systems

  • Output cable(s) for Digital Lynx SX and SX-M.
Sold Separately:
  • FLED Driver with Pulse 2.0 Software
    Stand-alone FLED Driver with 3 output channels for precision real-time stimulus sequencing and delivery. Software stores and triggers up to 255 user-defined sequences.
  • Omnetics 44 Litz FLED Tether, Omnetics 26 to uDB37 FLED Tether, HS-32/64-MUX-FLED
    Twisted pair stim tether. Connects headstage to acquisition system and transports current from FLED Driver to FLED modules.
