Birefringent Crystal LiNbO3

Overview:

Lithium Niobate (LiNbO3) is widely used in fiber communication devices as Birefringent crystal. It has good mechanical and physical properties and is ideal for optical polarizing components due to its wide transparency range and low cost. It is an excellent material in fiber communication applications such as isolators, circulators, beam displacers, and other polarizing optics.
