Motorized Variable Optical Delay Line
SICART'’s Motorized Variable Optical Delay Line provides precision optical path length adjustment of up to 1200 ps. Driven by a step motor, the MDL has a delay resolution of less than 10 µm (34 fs), and an extremely low backlash of less than 8 fs. In addition, its advanced motion design guarantees longevity for long-term continuous operation. Low insertion loss and high reliability make this device ideal for integration in optical coherence tomography (OCT) systems, network equipment and test
