Stanford LDC500 Laser Diode Controller

The LDC500 series are the ideal instruments for controlling the current and temperature of your laser diodes. They have the performance and features you expect from instruments costing twice as much.

The LDC501 has up 500 mA of output current with less than 1 μA of rms noise, while the LDC500 has up to 100 mA of current and less than 0.3 μA of noise. The LDC502 provides up to 2 A current. Both constant current and constant power modes are provided. The temperature controller provides 36W output power and is compatible with a wide range of temperature sensors. Overall temperature stability is 0.0005 °C/°C.

The instrument includes an intuitive front-panel display and a full suite of computer interfaces including RS232, GPIB and Ethernet.
