“臨牀化學分析儀紅外截止濾光片”詳細介紹
紅外截止濾光片(Infrared Cut-off Filter,簡稱IR Cut Filter)是一種光學元件,主要用於阻擋紅外光(波長通常大於700nm)而允許可見光(約400-700nm)通過。它在現代成像系統中應用廣泛,尤其在數碼相機、智慧手機攝像頭、安防監控等領域至關重要。
核心功能
阻擋紅外光:
自然光和人造光源中常包含可見光和紅外光。但圖像感測器(如CMOS/CCD)對紅外光敏感,若不濾除,會導致色彩失真(如紅色偏重、對比度下降)。
提升色彩還原度:
通過精確過濾紅外波段,確保感測器僅接收可見光,使成像顏色 接近人眼所見。
紅外截止濾光片的工作原理是什麼?
光譜選擇性:
濾光片通過特殊鍍膜或材料設計,在可見光波段(400-700nm)保持高透射率(>90%),而在紅外波段(如700-1200nm)透射率急劇下降(<5%)。
反射或吸收紅外光:
部分濾光片通過多層干涉膜反射紅外光,另一些則通過吸收性材料(如藍玻璃)實現。
如何區分真假紅外截止濾光片?
用紅外遙控器測試: 濾光片會阻擋遙控器的紅外信號(手機攝像頭無法看到遙控器發光)。
