SAW grade LN, LT crystals are the featured products of Beijing Scitlion Technology. Variation of SAW propagation velocity may arise from the fluctuation of crystal components, uncompleted crystal poling and crystal defects. So, to ensure the SAW propagation velocity consistent and to meet customer's higher and higher requirement on crystal quality, such strict measures as quality and precise component ratio control of Nb2O5 and Li2CO3 raw materials, curie temperature measurement, defects inspection as well as optimized crystal growth and poling process, are taken.

Innovation point: Through the crystal growth machine's modification in rotating and lifting system, the stability of crystal growth interface and growth rate become higher. Also the defects caused by the influence of crystal rotating and rising disturbance on the solid-liquid interface during the crystal growth process are reduced. 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. The ultra low gradient interface growth temperature field we self-designed make the quality of optical crystals much better.Other specifications are available on request.
