QXKJ提供N-BK7楔形窗口片系列产品，可消除干涉图样，并且有助于避免外腔反馈。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。QXKJ也提供许多基底材料和镀膜选项的平窗口片。
N-BK7在光谱的可见光和近红外区域具有出色的透过率。通常在紫外熔融石英的优点（即，在紫外光区域有较好透过率，且热膨胀系数更小）并非必需的情况下选择N-K7窗口片。这些窗口片可选未镀膜(350 nm - 2.0 μm)或在两个光学表面镀我们三种低损耗标准带宽减反膜(BBAR)之一的版本。标准宽带减反膜设计用于以下范围：350 - 700 nm (A膜)，650 - 1050 nm (B膜)或1050 - 1700 nm (C膜)。未镀膜窗口片的每个表面具有约4%的典型损耗，而宽带减反膜在指定波长范围上将每个表面的该损耗减小到Ravg< 0.5% ，并且对于0°与30°之间的入射具有良好性能。
