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. The housing size of 1, 2 and 4 channel models are respectively 174 x 86 x 37 mm3, 233 x 86 x 37 mm3 and 351 x 86 x 37 mm3.
