Physical form
tetragonal (a = b = 7.12 Å, c = 6.29 Å)
Features and Benefits
Birefringent yttrium vanadate crystals are ideal materials for optical polarizing components such as fiber optics or beam displacers. It is transparent over a large range and is a material of medium hardness and can therefore be polished to a high optical finish.
