Description

Birefringent Crystal YVO4

Overview:

The Yttrium Orthovanadate (YVO4) is a positive uniaxial crystal grown with Czochralski method. It has good mechanical and physical properties and is ideal for optical polarizing components due to its wide transparency range and large birefringence. It is an excellent synthetic substitute for Calcite (CaCO3) and Rutile (TiO2) crystals in fiber optical applications such as isolators, circulators, beam displacers, Glan polarizers and other polarizing optics.

General Specifications Of YVO4:

Dimension Tolerance (W±0.1mm) x (H±0.1mm) x (L±0.2mm)
Optical Axis Orientation ±0.5°
Surface Quality Better than 20/10 Scratch and Dig
Clear Aperture >90% Central
Surface Flatness λ/4@633 nm
Parallelism <15 arc seconds
Perpendicularity <10 arc minutes
AR Coating Upon Request
