LiNbO3 Wafers X-cut 0.5mm Thickness Lithium Niobate Crystal
Lithium niobium crystal (LN)LiNbO3 is widely used in SAW filter, optical waveguide, photoelectricity modulator, frequency multiplication transducer and information storage as a functional crystal with excellent physical feature of anti high temperature and anti canker.
It has stable mechanical performance, and will appear different special feature after being doped differently.
LiNbO3 crystal combines low cost, good mechanical and physical properties as well as high optical homogeneity. Therefore, LiNbO3 wedges have been widely used in fiber isolators and circulators.
The possible applications:
