Laser diode controller

Laser Drive Specifications Dual-Range Current Source: Offers two selectable output ranges — 0 to 200 mA and 0 to 500 mA. High Precision & Resolution: Delivers exceptional setpoint accuracy of ±0.05% of full scale. Resolution is 4 µA on the 200 mA range and 10 µA on the 500 mA range. Exceptional Stability: Provides short-term stability (1-hour) of <20 ppm and long-term stability (24-hour) of <40 ppm. Adjustable Compliance Voltage: Features a user-adjustable compliance voltage from 0 to 10 V. 4-Wire Voltage Measurement: Supports 4-wire laser forward voltage measurement with an adjustable voltage limit. Temperature Control (TEC) Specifications High-Power TEC Controller: Integrated 32W TEC controller for precise thermal management. Wide Temperature Range: Capable of controlling temperature from -100°C to 199°C. Exceptional Temperature Stability: Achieves short-term stability (1-hour) of ±0.004°C or better, and long-term stability (24-hour) of ±0.01°C. TEC Output: Bipolar, constant current source with a maximum output of ±4.0 A and maximum output power of 32W. Sensor Compatibility: Compatible with a wide range of temperature sensors, including thermistors, RTDs (resistive temperature detectors), and IC sensors (AD590, LM335).
