Hoya 吸收型中性密度濾光片

See More by Hoya

透過吸收 (而非反射) 減弱可見光
可堆疊多個濾光片以提升攔截效果
提供的光學密度介於0.1至4.0之間
也可預先安裝於 C 接環外框

這些濾光片在可見光區域內擁有高水準的光譜穿透特性，可透過吸收 (含極少的反射) 來減弱光線。通常，吸收型濾光片的中性與密度是材料與厚度的函數。由於Hoya中性密度濾光片具有特定光學密度，因此厚度只是玻璃類型的函數。這些濾光片在光線控制應用中非常有用，可用於量測檢測設備及成像中的曝光控制。光學密度上升時，光譜會發生變化。

光學密度會展示相加關係，例如，將光學密度值分別是0.6與0.9的濾光片進行堆疊可產生1.5的光學密度。光學密度與穿透率的關係由以下公式表示：T = 10^-OD x 100 = 穿透率百分比。

請注意: 由於供應鏈的問題，我們的套裝組件可能會使用其他的包裝方案來取代木箱交貨。如有任何問題，請聯絡 kits@edmundoptics.com.
