Andover長波通/短波通邊緣濾光片
- 產品型號：
- 更新時間：2026-02-06
- 產品介紹：Andover長波通/短波通邊緣濾光片常被稱為長波通（LWP）和短波通（SWP）濾光片，這些陡峭邊緣濾光片以它們在反射和透射區域之間的高轉換率來區分。這種高轉換率使它們成為熒光應用中的發射濾光片和測光中的順序分選濾光片的*選擇。它們也非常有用，作為雜散光或裝飾濾光片，以消除任何不希望的近帶輻射。

Andover長波通/短波通邊緣濾光片
- 低成本
- 寬波長選擇
- 提供比彩色玻璃濾光片更陡峭的過渡
Andover長波通/短波通邊緣濾光片通常被稱為長波通（LWP）和短波通（SWP）濾光片，這些陡峭邊緣濾光片以它們在反射和透射區域之間的高轉換率來區分。這種高轉換率使它們成為熒光應用中的發射濾光片和測光中的順序分選濾光片的*選擇。它們也非常有用，作為雜散光或裝飾濾光片，以消除任何不希望的近帶輻射。所有的Andover 長波/短波濾光片都由堅硬、耐用的*表面介電涂層構成，并能承受與任何高質量光學元件相關的正常清洗和處理。它們的薄膜結構基本上是一個改良的四分之一波疊加，使用干擾效應而不是吸收來隔離它們的光譜帶。與濾光片玻璃不同，濾光片對波長偏移不敏感，這些濾光片的波長隨入射角的增加而變短。該特性在需要微調50%切割或截止波長的應用中是有用的。所有標準邊緣濾光片可在50nm增量從400nm到1000nm。可以定制邊緣濾光片，并將按要求報價。
