短波通滤光片andover 产品详情
这些尖锐边缘滤光片通常被称为长波通（lwp）和短波通（swp）滤光片，其特征在于它们在反射和透射区域之间的高转换率。如此高的转换率使其成为荧光应用中的发射滤光片以及光度法中的排序滤光片的xxx选择。它们还可以用作杂散光或微调滤光片，以消除任何不需要的近带辐射。所有andover lwp / swp滤光片均由坚硬，耐用的d一表面介电涂层构成，可承受与任何高质量光学组件相关的常规清洁和处理。它们的膜结构本质上是经过修改的四分之一波长叠堆，利用干涉效应而不是吸收来隔离其光谱带。与滤镜不同 由于对波长随角度的变化不敏感，这些滤光器的波长随入射角的增加而变短。此功能在可能需要微调50％截止波长或截止波长的应用中很有用。所有标准边缘滤光片都可以从400nm到1000nm以50nm的增量递增。
