Our abundance experience at growing and mass production for Optical grade Lithium Niobate. 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.

All the wafers are under strict quality control and inspected. And also under the strict surface cleaning and flatness control as well.
