    Andover長波通濾光片
    這些尖銳邊緣濾波器通常被稱為長波通（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(zhuǎn)換率。如此高的轉(zhuǎn)換率使其成為熒光應(yīng)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(diào)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(gòu)成，可承受與任何高質(zhì)量光學(xué)組件相關(guān)的常規(guī)清潔和處理。它們的膜結(jié)構(gòu)本質(zhì)上是經(jīng)過修改的四分之一波長疊堆，利用干涉效應(yīng)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(diào)50％截止波長或截止波長的應(yīng)用中很有用。所有標(biāo)準(zhǔn)邊緣濾光片都可以從400nm到1000nm以50nm的增量遞增。
    ? Low-cost
    ? Wide slection of wavelengths
    ? Provide steeper transistion than color glass filters
