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.

Physical properties

Refractive Index η, Birefringence (Δn) and walk-off angle at 45° (ρ):
η _o= 1.9929 η _e= 2.2154 Δη = 0.2225 ρ=6.04° at λ 0.63 μm
η _o= 1.9500 η _e= 2.1554 Δη = 0.2054 ρ=5.72° at λ 1.30 μm
η _o= 1.9447 η _e= 2.1486 Δη = 0.2039 ρ=5.69° at λ 1.55 μm

Thermal Conductivity: A axis 5.32 W/(m.k), C axis = 5.10 W/(m.k)

Thermal Expansion: α_a= 4.43 x10^-6/ °C, α_c= 11.37 x10^-6/ °C

Thermal Optic Coefficient: dη _a / dT : 8.5x10^-6/ °C, dη _c / dT : 3.0 x10^-6/ °C

Physical form

tetragonal (a = b = 7.12 Å, c = 6.29 Å)
