特性
QXKJ提供楔形蓝宝石窗口片系列产品，这些楔形光学元件消除了条纹图案，并有助于避免腔反馈。窗口片用于保护激光输出不受环境的影响，适用于光束采样应用。这些蓝宝石窗口片可选未镀膜(150 nm-4.5 ?m)或两面都镀有宽带增透膜。-D增透膜指定在1.65 - 3.0 ?m的范围内，每个表面的平均反射率小于1.0%，而-E1增透膜指定在2.0 - 5.0 ?m的波长范围内，每个表面的平均反射率小于1.50%。
蓝宝石是需在高温和低温操作条件下具有较好可靠性、强度、宽透射范围，或低透过波前畸变的苛刻应用的理想材料。蓝宝石从紫外到红外波段是透明的，并且只能被除它自身以外的少数材料划伤。它是化学惰性的，在温度高达1,000 �C时仍不溶于水，酸和减。我们的蓝宝石窗口片切割成晶体的c轴与光轴平行。
