Product Description
Lithium niobium crystal (LN)LiNbO3 lens 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.
We manufacture LiNbO3 crystal lens professionally.
