4220-DR Laser Controller 1A/2A
The 4220-DR LaserSource is our most powerful laser driver in the 4200-DR Series, providing 2,000mA of laser driver current. Like the other drivers in the series, the 4220-DR offers an excellent combination of low noise, accuracy, and resolution, and works well with higher power LEDs and lasers.
Dual Range
One of the key new features of the 4220-DR is the dual range capability, which allows operation in either a 1,000mA range or 2,000mA range
Programmable PD Bias Voltage
Unlike other laser drivers, the 4220-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.
