Crystal Wedge Plate
Crystal wedge plates use crystal birefringence to split or combine two orthogonally linearly polarized beams. For example, a small-angle lithium niobate wedge prism combined with a yttrium iron garnet crystal can form a fiber isolator based on Faraday rotation. Yttrium orthovanadate crystal wedge plates can also be cemented together to form a Wollaston prism.

Electro-optic deflectors (EODs) are optical devices used to steer or deflect light beams by applying an electric field to a specialized optical crystal. Unlike mechanical beam steering systems that rely on moving mirrors, electro-optic deflectors enable high-speed, non-mechanical beam control with exceptional precision and responsiveness. They are widely used in laser scanning, optical communications, microscopy, laser printing, spectroscopy, and scientific research, where rapid and accurate laser beam positioning is essential.
