概述光学元件

双折射楔块

在电信 ,利用兼具高消光比和高透光率的微型双折射楔块,对偏振复用光信号进行分路或合并。

These YVO4  and LiNbO3 birefringent wedges produce a large angular separation between orthogonally polarized beams in a very small space making them useful for telecom applications including WSS, isolators, interleavers, and more.

Birefringent Wedge Capabilities

Choose YVO4 or LiNbO, and specify size, wavelength, and anti-reflection coating options to meet your exact requirements.
