Beam Displace
A Beam Displacer is a rectangular slab made by the birefringent crystal material. They can split the extraordinary ray and ordinary ray at certain spacing due to its large birefringence when the angle of incidence is 0 degree.
CRYLIGHT is dedicated to manufacturing high precision beam displacer. The YVO4 crystal is the most widely used material for beam displacers. It is often used in circulators, isolators, interleaves, and WSS.
