Tydex公司的每個THz低通濾波片上都附帶一個外圈封裝, 截止波長在13-94µm之間，通光波段透過率高達81-94%，其通光孔徑/外徑的尺寸分為：24/31mm, 35/44mm，47/60mm三種尺寸現貨供應，也可根據要求定制設計尺寸。太赫茲低通濾波片（THz Low Pass Filters）是一種常見的太赫茲光學元件，其作用是傳輸并阻斷短波長的太赫茲波，主要原理是基于色散，反射，散射，漫射，衍射和干涉理論。可用于THz光譜學，THz測試設備，太赫茲成像等應用領域。
太赫茲低通濾波片的應用:
天文，太空和航天領域
THz光譜學
電光研究領域
成像
材料研究
THz測試設備
傳感器和探測器
THz低通濾波片的特點:
在阻帶（通光范圍外）的透過率低（<0.1％）
在通光范圍內透過率高
工作波長從IR到mm波
帶外圈封裝
