ILX Lightwave LDX-3525B Series Laser Diode Driver

ILX Lightwave model: LDX3500

The ILX Lightwave LDX-3525B is part of the 3500 series family of low noise, high stability laser diode current sources and drivers specifically for precision control of low power laserss. It is a is a 500mA current source that offers robust integrated laser diode protection circuits. Slow start current set point, current limits and voltage limits offer a high level of laser diode protection. These drivers operate in either a constant current mode (CC) or a constant optical power mode (APC) to cover a wide range of research lab testing applications.

The LDX-3525B  was updated in year 2012 to integrate a USB interface as well as updated LabVIEW drivers to make user operation simple and remote communications fast.

These drivers are loaded with industry leading features such as dual current ranges and fine and coarse set point control through the front panel digital trim potentiometer control knob. They offer an external modulation capability. For automated testing applications in an R&D or production environment, remote operation is easily accomplished through the USB interface.
