Product Description
Lithium Niobium crystal (LN)LiNbO3 lens
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.

Innovation point: Through the growth equipment modification,we create simulation of crystal growth system and can design crystal shape. The computer chip control the changing of crystal shape according to crystal growth status, through the processing of precision sensor signals. We self-design a set of graded composite temperature structure. With the help of it, the temperature gradient in crystals, melt and the solid liquid interface reach the good state for optical crystal growth.
