產品概覽

用於調整 f/#、視場光闌直徑及總進光量
封裝版附接桿安裝用螺紋孔
多種型號適用於不同應用

標準系列可變光圈可控制經典光學系統中的系統 f/#（f/# = 焦距/有效直徑）、視場光闌直徑和總進光量。需要注意，光圈位置對系統的性能至關重要。從最大孔徑到最小孔徑（約 90°），所有型號的光圈均能在槓桿行程內實現流暢的機械變化。這些光圈的封裝版均有螺紋孔，便於安装接桿。標準系列可變光圈採用藍鋼彈簧結構和黑色外殼飾面，槓桿作動器有兩種樣式：不銹鋼「銷」或塑膠「片」。這些光圈專為OEM整合和一般實驗室使用而設計。

如需特定的OEM應用支持，請聯絡我們的應用工程部門

請注意：標準系列可變光圈安裝架單獨出售
