产品系列说明

具有 30 弧分楔形的 N-BK7 基材
λ/10 表面平整度，20-10 表面质量
消除标准具效应的理想选择
另外提供熔融石英楔形窗口片和 N-BK7 平窗口片

TECHSPEC® N-BK7 楔形窗口片提供标准公制尺寸，楔形为 30 弧分。这些窗口片的楔形通过防止背面反射沿着与透射光束相同的光路传播来消除标准具效应。在激光腔中，楔形窗口片有助于防止这些不必要的反射引起的激光不稳定性、模式跳跃和功率尖峰。TECHSPEC N-BK7 楔形窗口片通常用作Fused Silica Wedged Windows的经济高效替代品，用于不需要 UV 透射或不需要高热稳定性的应用，例如低功率可见光或 NIR 激光。楔形窗口片还可用作光束采样器或光束拾取光学元件，以监测激光光束特性，例如随时间变化的光束功率。
