General Photonics’ MDL-002 family of motorized variable optical delay lines allow optical path length adjustment of up to 560 ps in a single-pass. Driven by a DC motor with an integrated encoder, the MDL-002 has a delay resolution of less than 0.3µm (1 fs).

Three configurations of the MDL-002 are available:

  1. an integrated unit for use on the bench
  2. a two piece unit with the optical head and control unit separated for installation into customer equipment
  3. 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.

The delay line is available with either single mode or PM fiber pigtails.
