ScanDelay
Data Sheet

The ScanDelay is a special drive for high precision linear translation of an optical component, including a retroreflector. Typical use of the ScanDelay is in autocorrelators and pump-probe-experiments to generate an optical delay. The low mass and frictionless design of the device allows for a wide delay range as well as for high resolution and fast scans. The scanning movement follows a control signal either supplied by the driver unit or by an external source. An analog optical sensor continuously measures the actual position and provides a feedback signal for the integrated closed loop motion control.
