General Photonics’ motorised variable optical delay line provides precision optical path length adjustment of up to 560 ps, single-pass. Driven by a DC motor with an integrated encoder, the MDL-002 has a resolution of less than 0.3μm (1 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. The MDL-002 is available in three configurations:

• An integrated unit for use as a bench-top instrument for laboratory applications
• With the optical head and control unit separated for easy incorporation into other equipment
• An OEM version with a miniature controller board

All three versions can be remote controlled by a PC or a micro-processor through an RS-232 interface.
