      Sapphire (Al\u2082O\u2083) has long been recognized for its exceptional combination of optical clarity, mechanical strength, and chemical stability. Among various forms of sapphire, optical grade sapphire substrates stand out for their purity, defect control, and uniform crystallographic orientation, making them indispensable in advanced optical and high-pressure applications.
