用於工業 DIC 和雷射干涉測量系統的藍寶石光學窗口
Sapphire optical windows (single-crystal Al₂O₃) are widely used in advanced optical measurement systems such as Digital Image Correlation (DIC) and laser interferometry. Their exceptional hardness, high optical transmission range, thermal stability, and resistance to harsh industrial environments make them a preferred choice for high-precision metrology applications. This article provides a scientific overview of material properties,
