Ordering Code:
  • We have developed an assembly where the LED is an integral part of the fiber-optic cannula thus providing a lightweight optical source attached to the head of the animal suitable for deep brain illumination. The protruding optical fiber is implanted into the skull.

    To keep the assembly small and light, there is no heat sink. To avoid heating, the maximum current should be limited. 

    Note: A bare cable connection is provided to interface with a current source.

  • Electrical interface 3 pins header, 1.27 mm pitch
    Pinout Pin 1 & 3 : Cathode (-)
    Pin 2 (center) : Anode (+)
    Maximum Current
    150 mA (continuous)
    300 mA (10 ms pulse, 10% duty cycle)
    Dimensions 6 mm x 6 mm x 6 mm
