4205-DR Laser Controller 250mA/500mA
The 4205-DR LaserSource is our most popular laser driver in the 4200-DR Series, offering an excellent combination of low noise, accuracy, and resolution. The 4205-DR will work well in low power pump lasers, high power LEDs, and other applications requiring up to 500mA of drive current.
Dual Range
One of the key new features of the 4205-DR is the dual range capability, which allows operation in either a 250mA range or 500mA range
Programmable PD Bias Voltage
Unlike other laser drivers, the 4205-DR includes a software programmable PD bias voltage, from 0 to -5V, so selecting your bias voltage has never been easier. Simply adjust the voltage in the user menu or via a software command… no more fumbling around with a DMM and screwdriver to adjust the trim pot.
