This unit
The ILX Lightwave LDX-3232 is a precision laser diode driver engineered for meticulous current and temperature control in research, development, and industrial environments. It delivers stable, accurate operation across a 0 mA to 300 mA output range with ±1 µA stability and ±0.05% accuracy, supported by integrated thermoelectric cooling with ±0.01°C temperature stability. Built-in protection features - soft start, adjustable current limiting, transient suppression, and safety interlock - safeguard laser diodes during operation. The instrument provides real-time monitoring of output current, laser mount temperature, and photodiode feedback, with flexible modulation capabilities including internal sine wave generation (1 Hz to 100 kHz) and external DC-coupled inputs (0 V to 5 V). GPIB and RS-232 interfaces enable remote automation and data acquisition.
