VDL-004
Miniature Variable Optical Delay Line
The VDL-004 manual variable optical delay line is a small, short range delay line that allows a user to adjust the delay to a desired position and then lock it in place.
Product Description
甚高频数据链- 004是一种延迟线和光纤耦合delay adjustment path in free space. The delay is adjusted by manually turning a dial on one end of the device, and the position is read from a scale on the front. The device includes a locking screw to lock the position setting. This device offers continuous control with high precision, zero backlash, and good thermal stability. Convenient mounting brackets allow mounting in any orientation, as well as easy integration of multiple units on a base plate to form an array.
The delay line is available with either single mode or PM fiber pigtails.
Solutions and Applications
The VDL-004 is designed for OEM applications that require short-range optical path adjustment to find an optimal position and then lock it in place, especially for multichannel path matching. Applications include phased array antennas, microwave photonics, coherent detection systems, optical time domain multiplexing (OTDM), optical coherence tomography (OCT), optical interferometry, optical Fourier spectrum analysis, and fiber sensors.
