QXKJ提供N-BK7楔形窗口片系列產品,可消除干涉圖樣,并且有助于避免外腔反饋。窗口片用于保護激光輸出不受環境的影響,適用于光束采樣應用。QXKJ也提供許多基底材料和鍍膜選項的平窗口片

N-BK7在光譜的可見光和近紅外區域具有出色的透過率。通常在紫外熔融石英的優點(即,在紫外光區域有較好透過率,且熱膨脹系數更小)并非必需的情況下選擇N-K7窗口片。這些窗口片可選未鍍膜(350 nm - 2.0 μm)或在兩個光學表面鍍我們三種低損耗標準帶寬減反膜(BBAR)之一的版本。標準寬帶減反膜設計用于以下范圍:350 - 700 nm (A膜),650 - 1050 nm (B膜)或1050 - 1700 nm (C膜)。未鍍膜窗口片的每個表面具有約4%的典型損耗,而寬帶減反膜在指定波長范圍上將每個表面的該損耗減小到Ravg< 0.5% ,并且對于0°與30°之間的入射具有良好性能。
