LDX-3220 Newport Precision Laser Diode Current Source

The LDX-3200 Series Precision Laser Diode Drivers are a best-in-class family of high precision microprocessor-based instruments that offer a high stability, low noise current source with integrated laser diode protection circuits, specifically for controlling laser diodes. A recent addition to the LDX-3200 Series, the NEW LDX-3232 was developed for controlling high compliance voltage devices such as quantum cascade laser diodes with the same low noise, high stability performance of the series. These laser diode drivers are known throughout the industry for their reliability, precision, and ease-of-use.

The LDX-3200 Series consists of laser diode drivers with current ranges of 50/100mA (LDX-3210), 200/500mA (LDX-3220), and 2A/4A (LDX-3232) covering a wide range of laser diode testing and control applications. In addition to precision current control, the LDX-3200 Series products are loaded with standard features such as dual current ranges, constant power control, fine/coarse set point control, four-wire forward voltage measurement, and external modulation capability.

Furthermore, all of ILX Lightwave’s proven laser diode protection strategies including adjustable current and voltage limits, intermittent contact protection, and output shorting relays are designed into each model.

For automated testing applications in an R&D or production environment, remote operation is easily accomplished through the GPIB/IEEE-488 interface. For virtual instrument programming, LabVIEW® instrument drivers are available in the menu on the right.
