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.Optical grade lithium tantalate crystals and wafersLithium tantalate optical filmVarious lithium tantalate LT shaped blocksPhotos:SAW Level LT ingotOptical LT wafersPacking
