Beam Displacer

Product Description

Hobbite® Telecom Optics (Beam Displacer)

YVO4 is a positive uniaxial crystal and has good mechanical and physical properties therefore is ideal for optical polarizing components because of its wide transparency range and large birefringence. YVO4  is an excellent synthetic alternative for Calcite and Rutile (TiO2) crystals in many applications including fiber optic isolators, circulators, beam displacers, Glan polarizers and other polarizing optics.
