We use high-purity single-crystal Al₂O₃and optical-grade sapphire materials, all with a purity of 99.999%. Our company can manufacture Epi-ready sapphire wafers with very low surface roughness. We can provide sapphire windows with good transmittance and excellent optical performance. We can also provide patterned sapphire substrates and sapphire ingots.
