4201-DR Laser Controller 50mA/100mA
The 4201-DR LaserSource is well suited for low power applications, offering an excellent combination of low noise, accuracy, and resolution. If your working with VCSELs, quantum dot lasers, or other low power devices, the 4201-DR provides a very precise, very accurate driver well suited for these types
Dual Range
One of the key new features of the 4201-DR is the dual range capability, which allows operation in either a 50mA range or 100mA range
Programmable PD Bias Voltage
Unlike other laser drivers, the 4201-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.
