中性密度吸收滤光片
这些滤光片在可见光区具有水平光谱透射率特性，并通过小反射衰减吸收光。通常，吸收过滤器的中性和密度是材料和厚度的函数。由于霍亚中性密度滤光器被保持在一个特定的光学密度，厚度只是玻璃类型的一个函数。它们在光控制应用中很有用，用于测量仪器和成像中的曝光控制。光谱变化发生在光学密度增加时。光密度表现为加性关系;例如，用OD值为0.6和0.9的堆叠过滤器产生的密度为1.5。光密度与传输由以下方程:T = 10 ^ od x 100 =?传输%。
中性密度吸收滤光片。
#55-222在光学密度值为0.15、0.3、0.4、0.6、0.9和2.5中包含6个滤波器。带有泡沫衬里的木箱。
#63-468，#63-469，#63-470和#66-155每一个包括14个滤光密度值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。请注意，OD 3.0是这些工具包中*不包含的。带有泡沫衬里的木箱。
