The LDT-5940C Thermoelectric Temperature Controller combines precision temperature control with an intuitive instrument front panel for fast, accurate temperature control of laser diodes and other optoelectronic components. The LDT-5940C was designed for customers requiring higher power and high stability.
This temperature controller with digital PID control loop achieves temperature stability of less than 0.003°C with output current noise and ripple less than 2mA rms. Fast setup is accomplished with preset PID values or by using the auto-tune function. Users can also manually enter PID values.
The LDT-5940C includes IEEE 488.1 GPIB and USB 2.0 computer interfaces for easy integration into any R&D or manufacturing application. For virtual instrument programming, LabVIEW® instrument drivers are available free of charge. LabVIEW® instrument drivers can be downloaded from the Literature and Downloads tab on this page.
