微型可变光学延迟线

VDL-004手动变量光学延迟线是一个小型短程延迟线,允许用户将延迟调节到所需位置,然后将其锁定到位。

产品描述

VDL-004是具有自由空间中的延迟调节路径的光纤耦合延迟线。通过手动在设备的一端手动转动拨号调整延迟,并且从前面的刻度读取位置。该装置包括锁定螺钉,以锁定位置设置。该装置提供连续控制,具有高精度,零间隙和良好的热稳定性。方便的安装支架允许在任何方向上安装,以及轻松集成底板上的多个单元以形成阵列。

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

解决方案和应用程序

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.
