长波通/短波通边缘滤光片

• 低成本
• 宽波长选择
• 提供比彩色玻璃滤光片更陡峭的过渡

通常被称为长波通（LWP）和短波通（SWP）滤光片，这些陡峭边缘滤光片以它们在反射和透射区域之间的高转换率来区分。这种高转换率使它们成为荧光应用中的发射滤光片和测光中的顺序分选滤光片的极好选择。它们也非常有用，作为杂散光或装饰滤光片，以消除任何不希望的近带辐射。所有的Andover 长波/短波滤光片都由坚硬、耐用的**表面介电涂层构成，并能承受与任何高质量光学元件相关的正常清洗和处理。它们的薄膜结构基本上是一个改良的四分之一波叠加，使用干扰效应而不是吸收来隔离它们的光谱带。与滤光片玻璃不同，滤光片对波长偏移不敏感，这些滤光片的波长随入射角的增加而变短。该特性在需要微调50%切割或截止波长的应用中是有用的。所有标准边缘滤光片可在50nm增量从400nm到1000nm。可以定制边缘滤光片，并将按要求报价。
