The MDL-002 from Luna Innovations is a Motorized Variable Optical Delay Line that operates at a wavelength from 840 to 1650 nm. It has an optical delay rate of 0 - 1120 ps and a position accuracy of ±6 μm. This optical delay line has an insertion loss of less than 1.5 dB and a return loss of 50 dB. It can handle an optical power of up to 300 mW and requires a DC supply of 12 V consuming 1 A of current. It can be controlled via a panel keypad & RS-232 interface.
The MDL-002 is available in 3 configurations:
1) an integrated unit for use as a bench-top instrument for laboratory applications,
2) with a separate optical head and control unit for easy incorporation into other equipment, and
3) an OEM version with a miniature controller board.
This optical delay line is available in an optical head module that measures 6.18 x 1.46 x 0.7 inches and has SMF-28 or PM Panda fiber. It is ideal for Optical Coherence Tomography (OCT), optical Fourier spectrum analysis, optical interferometry, delay generation & measurement, optical time-division multiplexing (OTDM), and fiber sensor applications.
