This unit
The ILX Lightwave CSM-39020 is a 4-channel laser diode current source module engineered for integration into the LDC-3900 Modular Laser Diode Controller. It delivers precision current control with low noise and high stability, essential for demanding laser applications requiring accurate output regulation. The module features fully isolated channels, internal calibration storage, and support for photodiode feedback control and modulation input. Its modular design enables hot-swap installation and interchangeability with other LDC-3900 modules while retaining calibration data across system reconfigurations.

Laser diode biasing and modulation in research and instrumentation
Optical communication system testing
Precision spectroscopy and metrology
Wavelength-tunable laser control
Compatibility & Integration Designed exclusively for the ILX Lightwave LDC-3900 Modular Laser Diode Controller. Slides into any of four available bays. Compatible with GPIB/IEEE-488.2 remote programming and readout through the mainframe. Directly interchangeable with other LDC-3900 modules including TEC and combination modules. All module configuration is transparent to the host system - the LDC-3900 mainframe automatically detects installed modules and reverts to default parameters upon hardware changes, while module calibration data remains independent and persistent.
