YVO4
(Yttrium orthovanadate)
YVO4(Yttrium
orthovanadate) is a positive uniaxial crystal grown with Czochralski method. It
has a wide transparency range and larger birefringence, which make it widely
used in many applications in particular fiber optics field. YVO4
is an excellent synthetic substitute for calcite and rutile crystal.
Red
