Andover短波通濾光片
這些尖銳邊緣濾光片通常被稱(chēng)為長(cháng)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(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(zhì)量光學(xué)組件相關(guān)的常規清潔和處理。它們的膜結構本質(zhì)上是經(jīng)過(guò)修改的四分之一波長(cháng)疊堆,利用干涉效應而不是吸收來(lái)隔離其光譜帶。與濾鏡不同 由于對波長(cháng)隨角度的變化不敏感,這些濾光器的波長(cháng)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(cháng)或截止波長(cháng)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。
