SRS LDC500 Series 36W Laser Diode Controller with 0.001 °C Resolution and GPIB RS-232 Ethernet Interfaces

The LDC500 Series Laser Diode Controllers are highly stable, low-noise current sources with integrated temperature controllers, offering exceptional performance at affordable prices. These instruments provide the ideal solution for controlling current and temperature of laser diodes with features typically found in instruments costing twice as much.

The series includes three models: LDC500 (up to 100 mA), LDC501 (up to 500 mA), and LDC502 (up to 2 A). Each features a low-noise current source, 36 W high-precision temperature controller, and standard computer interfaces including Ethernet, making them the right choice for laser diode testing and control applications.

• 100 mA, 500 mA or 2 A source options
• Ultra-low drift (<10 ppm/°C)
• <0.3 µA current noise (LDC500)
• GPIB, RS-232 and Ethernet interfaces

• 36 W output power
• Ultra-high stability (0.0005 °C/°C)
• Auto-tuning of loop parameters
• CC & CT mode dynamic switching
