中性密度吸收濾光片
這些濾光片在可見光區具有水平光譜透射率特性，并通過小反射衰減吸收光。通常，吸收過濾器的中性和密度是材料和厚度的函數。由于霍亞中性密度濾光器被保持在一個特定的光學密度，厚度只是玻璃類型的一個函數。它們在光控制應用中很有用，用于測量儀器和成像中的曝光控制。光譜變化發生在光學密度增加時。光密度表現為加性關系;例如，用OD值為0.6和0.9的堆疊過濾器產生的密度為1.5。光密度與傳輸由以下方程:T = 10 ^ od x 100 = 傳輸%。
中性密度吸收濾光片。
#55-222在光學密度值為0.15、0.3、0.4、0.6、0.9和2.5中包含6個濾波器。帶有泡沫襯里的木箱。
#63-468，#63-469，#63-470和#66-155每一個包括14個濾光密度值0.1,0.15,0.2,0.3,0.4,0.5,0.6,0.7,0.9,1.0,1.3,1.5,2.0和2.5。請注意，OD 3.0是這些工具包中*不包含的。帶有泡沫襯里的木箱。
