lithium niobate wafer

SAW Grade Lithium Niobate Wafers
Our abundance experience at growing and mass production for SAW grade Lithium Niobate crystal wafers. We are equipped with advanced facilities at Crystal growing, wafer lapping, polishing and checking, all finished products are passed at Testing of curie Temp and QC inspection.
Our R&D is active at developing and researching from new material to finished products at all kinds of optical doped wafers & electronic components.
CQT produce the products:single piezo crystal, quartz blanks, Single Quartz Blanks, lithium niobate wafer and lithium tantanlate wafer. We has been servicing for microelectronic manufacturers, defense related contractors, National laboratories, universities and scientists around the world since 1990
