Product Description

Watch “glasses” manufactured on the base of leucosapphire and light-colored sapphires are used by all well-known manufacturers of high-quality watches. This is not a fashion. You will see no scratches on such “glasses.”

Although there are lots substrates which are regarded as potential materials to replace Sapphire Substrate, it is still dominated in the substrates (for GaN LED growth) market, because of its reasonable price and relatively low mismatch. Zhongju is capable of processing substrates according to customer needs. Currently, our sapphire substrate productions ranges from 2 to 12 inches with high quality and accurate orientation.
