  • 詳細內容

Andover短波通濾光片

這些尖銳邊緣濾光片通常被稱為長波通（LWP）和短波通（SWP）濾光片，其特征在于它們在反射和透射區(qū)域之間的高轉換率。如此高的轉換率使其成為熒光應用中的發(fā)射濾光片以及光度法中的排序濾光片的**選擇。它們還可以用作雜散光或微調濾光片，以消除任何不需要的近帶輻射。所有Andover LWP / SWP濾光片均由堅硬，耐用的**表面介電涂層構成，可承受與任何高質量光學組件相關的常規(guī)清潔和處理。它們的膜結構本質上是經過修改的四分之一波長疊堆，利用干涉效應而不是吸收來隔離其光譜帶。與濾鏡不同 由于對波長隨角度的變化不敏感，這些濾光器的波長隨入射角的增加而變短。此功能在可能需要微調50％截止波長或截止波長的應用中很有用。所有標準邊緣濾光片都可以從400nm到1000nm以50nm的增量遞增。
