The LDC-3900 Modular Laser Diode Controller may be configured as a combination current source/temperature controller. It may also be configured with only current sources or only temperature controllers. The current sources provide high stability outputs with fully redundant current limit and multiple laser protection features. The temperature controllers can work with most thermistors and TE modules to deliver precision laser temperature control over a wide range of temperatures. The LDC-3900's fast, sophisticated GPIB lets you automate your experiment.
