PRODUCT INTRODUCTION

MDL-002

Motorized Optical Delay Line Module

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

MAIN SPECIFICATIONS

PRODUCT DESCRIPTION

The MDL-002 is a fiber coupled delay line with the delay adjustment path in free space. It is driven by a DC motor with integrated encoder, and combines delay ranges of up to 560 ps single pass with scan speeds of up to 256 ps/s. 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, and 3) an OEM version that replaces the control unit with a miniature controller board.

All three versions can be remote controlled via RS-232. The standard controller unit also has an integrated keypad and LCD display. The delay line is available with either single mode or PM fiber pigtails.

PRODUCT SOLUTIONS

The MDL-002 is useful for optical path adjustment of up to several cm. Applications include optical coherence tomography (OCT) and other interferometric systems, multichannel path matching in laser systems, and network optical length control and timing alignment. An MDL can be used in conjunction with a fiber stretcher or phase shifter for coarse and fine delay adjustments.
