VODL

1 – Description
The Variable Optical Delay Line (VODL) is a device that enables a very precise and stable control of an optical
path length up to 3ns.
The product has one input and one output. The optical delay can continuously be tuned thanks to a
micrometer head (manual option) or a motorized actuator (piloted option).
Our VODL products are athermal and don’t need any external control to stabilize the optical path delay.
