This addition to the MDL product line is specifically designed for OEM applications that require continuous scanning capability and a small footprint. The standard device has a delay range of 100 ps. An internal mirror can also be installed to cause light to double pass the device, doubling the delay range. A stepper motor and two position sensors ensure precise delay control. 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. A mini controller board is available as an accessory. Timing/Delay Modules Miniature Motorized Variable Optical Delay Line – VariDelay™ II
