Motorized Variable Optical Delay Line (300 - 600 ps)
YESWEHAVE’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 instruments for precision optical path length control or timing alignment.

*Above specifications are measured at center wavelength without connector. For devices with connectors, IL increases by 0.5 dB, RL decreases by 5 dB, ER decreases by 2 dB.
**Absolute delay at 0 ps setting measured to the edge of the enclosure (excluding caps, boots, and pigtails).
***The output pigtail can be replaced with a reflector to create a double pass device.
