The ILX Lightwave LDC-39100 is a 1 A Current Source Module (CSM) designed for precision laser diode control within the LDC-3900 Modular Laser Diode Controller mainframe. This service-free module delivers high-stability, low-noise output with on-module calibration data storage and closed-case calibration capability. It integrates into any of four interchangeable module bays, enabling flexible system configuration alongside TEC modules and combination units. The CSM-39100 supports photodiode feedback control, modulation input, and both local and remote calibration via GPIB interface.

– Compatibility & Integration
Designed exclusively for the ILX Lightwave LDC-3900 Modular Laser Diode Controller mainframe. Interchangeable with other LDC-3900 series modules, including current source variants (200 mA to 8 A), thermoelectric cooler (TEC) modules (up to 32 W), and combination current source/TEC modules. The LDC-3900 mainframe provides four rear-loading bays, 4 independent channels with 8 isolated outputs, and supports standard GPIB IEEE interface (optional).
