Equations have been derived that allow differences in reflectometer readings of the same sample with various reflectometers to be minimized by placing all reflectances on an absolute basis. For pigmented vehicle films the Fresnel reflectances and transmittances at the air-vehicle interface can be calculated for an arbitrary incident angular light distribution. The form of the reflected and transmitted angular distributions can also be calculated. The equations have been used to determine absolute reflectances of titanium dioxide pigmented films from meter readings of two reflectometers-the General Electric Recording and the Colormaster.
已经推导出来一些方程式，通过将所有反射率置于绝对基础上，可使同一样品在不同反射仪上的反射仪读数差异最小化。对于有色载体薄膜，对于任意入射角光分布，都可以计算出空气 - 载体界面处的菲涅尔反射率和透射率。反射和透射角分布的形式也可以计算出来。这些方程式已被用于根据两台反射仪（通用电气记录型和色彩大师型）的测量读数来确定二氧化钛着色薄膜的绝对反射率。
