LED Drivers

Doric programmable LED Drivers are available in 1-, 2-, and 4-channel versions. When connected to a Connectorized LED having an eprom memory, the LED Driver recognizes the LED wavelength and automatically sets the maximum current value to avoid accidental overdriving.

Doric programmable LED Drivers are available in 1-, 2-, and 4-channel versions. When connected to a Connectorized LED having an eprom memory, the LED Driver recognizes the LED wavelength and automatically sets the maximum current value to avoid accidental overdriving.

In stand-alone mode, all LED Drivers allow cw operation and external analog modulation through an input BNC connector for each channel. For each channel, there is also a current monitoring BNC output allowing data acquisition or triggering of other devices. When using Doric Neuroscience Studio Software, more advanced operating modes are available such as TTL modulation and software defined illumination sequences, thus eliminating the need for a function generator. In low-duty cycle pulsed mode, the software allows to overdrive the LED sources if a higher power is needed. For multiple channel driver versions, each channel is controlled independently. Although not mandatory for LED sources, our LED Drivers come with a safety interlock connector and a main key switch. These safety features are of interest for UV and near infrared LEDs.

Notes:

  • The renewed line of Doric LED Drivers has a new connector pinout that does not include pins for fan power. It is thus essential to use a Fan Power Adapter when using Combined LEDs or Combined LEDs with a Fiber-optic Rotary Joint. This power adapter is suitable for up to 4 channels and is sold with corresponding M8 cables.
  • The 8-channel LED Driver is available on request.

    Doric Connectorized LEDs couple high brightness LEDs into an FC receptacle compatible with an FC connectorized fiber-optic patch cord. Each Connectorized LED is actively aligned for optimum output power and its optical design provides the maximum fiber-coupling efficiency into multimode optical fibers.
