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。
