The LDC-3900 Modular Laser Diode Controller features

four channels with eight isolated outputs for controlling
multiple laser diodes. Modules include current sources with
maximum outputs from 200mA to 8A, TE (thermoelectric)
controller modules with up to 32W of power and voltage
measurement, and controller modules with laser control
from 200mA to 2A and integrated 12W TE control.

An independent power supply powers each channel,

providing protection and stability for your laser diode. Every
module incorporates low noise, high stability performance,
and ILX Lightwave’s unmatched laser diode protection
topologies including independent current limits and laser
diode shorting relays.

Remote communication through an IEEE/GPIB interface

simplifi es testing and control of multiple devices. LabVIEW

®

drivers are also available for any combination of mainframe
and module.

TEC MODULE NOTES:

1

All values relate to a one-hour warm-up period.

2

Software limits of range. Actual range possible depends on the physical load, thermis

tor type, and TE module used.

3

Accuracy fi gures are quoted for a typical 10k

Ω thermistor and 100µA current setting.

Accuracy fi gures are relative to the calibration standard. Both resolution and accuracy

are dependent upon the user-defi ned confi guration of the instrument.

4

Accuracy depends upon the the sensor model selected, the calibration standard,

and the user-defi ned confi guration of the instrument.
