The CCVA-L-KT Computer Controlled Variable Attenuator Kit is an easy to use kit for the continuous, automatic attenuation of the laser output power. The algorithm used to control power operates in a closed loop with PID (proportional, integral, derivative) feedback, compensating for slow changes in output power.

The software included with this product is for reference only. It has been tested in the experimental setup described in the application note.
