Lithium niobate crystal, referred to as LN, belongs to the trigonal crystal system with a distorted perovskite-type structure. The LiNbO3 crystal exhibits manifold useful properties, including piezoelectric, ferroelectric, photoelectric, nonlinear optical, thermoelectric, etc. SAW grade LN wafers are wafers assigned to usages for Surface Acoustic Wave (SAW) devices, which convert acoustic waves to electrical signals by exploiting the piezoelectric effect of the materials. Compared with the normal lithium niobate, the saw grade niobate could be discriminated by higher near ultra-violet absorption and lower pyroelectric charge attributed to higher electrical conductivities. As a SAW-grade material, the competitiveness of LiNbO3 is composed of high electromechanical coupling factors and low insertion loss, which allow the LN wafer to transform the energies with high efficiencies. 

Shanghai North Optics offers the SAW grade lithium niobate (or LiNbO3) crystals and wafers, advanced facilities are equipped, and cutting-edge techniques are utilized for crystal growth, wafer cutting, wafer lapping, wafer polishing and wafer checking, all finished products pass Curie Temp testing and stringent QC inspections. Our LiNbO3 Wafers could be integrated into various SAW devices such as resonators, filters, and delay lines with excellent fitness. SAW grade or acoustical grade LiNbO3 crystals are available in the form of boules or ingots, blanks, wafer blanks, and polished wafers. Optical Grade LiNbO3 Crystal Wafers, MgO:LiNbO3 crystals for EO application, Nonlinear LiNbO3 and MgO:LiNbO3, and MgO:PPLN Crystals are also available.
