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。

Optical Density exhibits an additive relationship; for example, stacking filters with OD values of 0.6 and 0.9 yields a resultant density of 1.5. The optical density is related to the transmission by the following equation:
T = 10-OD x 100 = Percent Transmission.

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.
