We use all 99.999% high purity single crystal Al₂O₃ and optical grade sapphire materials. Our company is capable of producing 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.
