Sapphire Custom-shaped Optical Windows Optical Components
Sapphire irregular optical windows are precision-machined optical components fabricated from high-purity single-crystal aluminum oxide (α-Al₂O₃). Their core advantage lies in combining sapphire's inherent material properties with custom geometric designs to meet extreme environmental demands for optical, mechanical, and chemical performance.
