產品系列說明

使用 30 弧分楔形的 N-BK7 基材
λ/10 表面平整度及 20-10 表面品質
適用於消除標準具效應
也供應熔融石英楔形窗鏡及 N-BK7 平板窗鏡

TECHSPEC® N-BK7 楔形窗鏡供應含 30 弧分楔形的標準公制尺寸。本系列窗鏡的楔形設計，可避免背部表面反射沿著與穿透光束相同的光學路徑行進，以消除標準具效應。楔形窗鏡在雷射腔之中，可協助避免前述不需要反射造成的雷射不穩定、模式跳換及功率峰值。TECHSPEC N-BK7 楔形窗鏡常在不需要紫外線穿透的應用，或是在低功率可見光或近紅外線雷射等不需要高度熱穩定性的應用中，作為符合成本效益的熔融石英楔形窗鏡替代方案。楔形窗鏡也可作為光束取樣器或光束拾取光學元件，以監控長期光束功率等雷射光束屬性。
