產品系列說明

  • 光譜平直
  • 適中的價格擁有最優的準確性與中性特質
  • 使用堆疊可建立適中的密度值

這些濾光片在整個表面上的密度值保持恆定。穿透與反射的比率視選取的密度而不同。在堆疊中,總密度是每個濾光片之密度的總和。中性密度濾光片主要用於減弱廣闊的光譜範圍內的光線。這些濾光片通常用於功率過高會導致裝置損傷或結果不準確的雷射與光度計應用。請以0° 入射角將反射面一側面向光源。

光密度值運算時遵循加法關係;比如,由一個0.6光密度和一個0.9光密度的兩個濾光片疊加而成的濾光片的光密度值為1.5。穿透率和光密度之間有如下方程的關係:穿透率=10-光密度 X 100=穿透率百分值。


請注意:低光密度濾光片(0.1、0.15和0.2外徑)鍍有薄薄的鉻鎳合金鍍膜,其性能可能會隨著時間使用而發生變化。為了延長濾光片的使用壽命,建議使用非接觸式清潔方法(如壓縮空氣),並避免在潮濕環境中使用濾光片以防止氧化。使用溶劑等接觸式清潔方法會損壞塗層,產品將不再符合網站標示規格。


請注意:由於供應鏈的問題,套件組可能會用其他包裝方案來代替木箱交貨。若有任何問題,請聯絡 [email protected].

Reflective Neutral Density Filter Kits

Reflective Neutral Density Filter Kits are available with either 8 or 14 optical densities. The kits with 8 filters include our most popular filters, with densities of 0.3, 0.5, 1.0, 1.3, 1.5, 2.0, 2.5, and 3.0. The kits with 14 filters include all available densities, except for 3.0. Kits are ideal for determining precise system optical density requirements. Custom densities are available for OEM applications.
