• Three models with source current from 200 mA to 6A
• High stability, low noise current source specifically for laser diodes
• Constant current and constant power operating modes
• Analog current modulation input
• USB 2.0 computer interface

The new LDX-3500B Series Laser Diode Drivers are a family of low noise high stability current sources specifically for precision control of low to high power laser diodes. Three models with a maximum output current range from 200 mA to 6A operate in constant current or constant optical power modes to cover a wide range of laser diode testing and control applications. In additional to precision current control, the LDX-3500B Series drivers also feature photodiode current measurement for constant power control, analog modulation for power and wavelength tuning, and an analog output for remote monitoring.

All of ILX's proven laser diode protection strategies are designed into each model with includes adjustable current limits, shorting relays, slow turn-on circuits, and transient protection during power up and laser operation.

A new front panel for the LDX-3500B Series instruments allows for quick and easy operation. Error indicators help resolve set-up problems quickly such as open circuit and current and power limits.

The new USB interface and control software allows for fast, repeatable instrument control during R&D and manufacturing testing and other control applications.
