LED Fiber Light Source

LED Fiber Light Source


Ordering Code:

  • The LED Fiber Light Source is an assembly of 1, 2, or 4 independent LEDs and their driving electronics into a compact housing. Each LED has its own output FC connector. The functionalities and software of Doric LED Fiber Light Sources are identical to those of LED Drivers. When ordering multi-channel models, any combination of LED wavelengths can be chosen.

    Doric light sources can be controlled using the Doric Neuroscience Studio, allowing more complex forms of light source control than through standalone use.  For example, it is possible to program simple or complex light pulse train sequences and to control their start with an external trigger signal in multiple different ways, see the trigger presentation video.

    If your application requires control of the device with another software, we can provide the API to control from Matlab, Python, or C++, please contact our technical support for more details.

    Note: AC/DC power supply is supplied to match customer location electrical outlet standard.
