Laser Diode Module Drivers

Laser Diode Module Drivers

Each channel has a BNC input connector for up to 10 kHz TTL/analog modulation of the driving current and a BNC output connector for monitoring the driving current or for the synchronization with other devices. Its laser safety features include a rear panel interlock connector, a master key switch and white LED illuminated control knobs indicating laser diode operation. Unlike most commercial laser diode drivers, our linear driving electronics eliminates leakage current to get no light output for zero set current. That means no residual light exits from the laser diode source when the driving current is set to zero, which is an important feature for optogenetics experiments. The Laser Diode Module Driver recognizes the Connectorized Laser Diode Module and automatically sets the maximum driving current, thus preventing accidental overdrive.

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 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.
