Notes:
Specifications in table apply for a single-pass device without connectors, measured over
1310 ± 50 nm or 1550 ± 50 nm. The output pigtail can also be replaced with a Faraday
mirror to create a double pass device with a total range of 200 ps. Some specifications will
change for this case.

General Photonics’ motorized variable optical delay line provides low cost, precision optical
path length adjustment and delay scanning functionality. 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.
