高效能od 4.0低通濾光片

High Performance OD 4.0 Shortpass Filters

×
  • 穿透與攔截範圍大
  • 坡度陡峭,可有效辨別光譜
  • 結合高通濾光片打造自訂帶通範圍

這些高效能低通濾光片經過精心設計,在阻隔頻譜內具有無與倫比的阻隔能力,在通過頻寬內具有最高的穿透率。這些濾光片的阻隔頻譜光學密度為4.0,在通過頻譜內的穿透率不低於91%,非常適用於多種應用。

將其與我們的TechSpec® OD 4.0 高效能高通濾光片合併,可建立客製的精密帶通濾光片。VIS 低通濾光片套件包含 400-700nm 之間的 7 個濾光片,均適合與濾光片旋轉輪整合。
