Laser Diode Driver, Precision, 500mA, 7V, USB, 120 VAC [Discontinued]
![Precision Laser Diode Drivers with USB [Discontinued]](https://api.p1.mks.com//medias/sys_master/DefaultCelumAssetsFolder/h4b/hf6/9901206962206/3525b_S-O_800w/3525b-S-O-800w.jpg)
The LDX-3525B Laser Diode Driver is a 500 mA microprocessor-based current source that offers a high stability, low noise output and integrated laser diode protection circuits. In addition to precision current control, the LDX-3525B Laser Diode Driver is loaded with standard features such as dual current ranges, constant power control, fine/coarse set point control, and external modulation capability. For automated testing applications in an R&D or production environment, remote operation is easily accomplished through the USB interface. For virtual instrument programming, LabVIEW® instrument drivers are available free of charge. LabVIEW® instrument drivers can be downloaded from the Literature and Downloads tab on this page.
We offer a wide variety of precision laser diode mounts with plug and play compatibility with our laser diode instrumentation.
