Absolute Calibration of a Scatterance Meter
A new method has been developed for determining the absolute calibration of a light-scattering meter. The method is applicable when the light source is a well-collimated beam of small diameter, such as from a laser. No special reflectance or transmittance standards are required and the method is simple to implement. The measured calibration factor includes refractive effects at water/glass/air interfaces as well as the changes in scattering volume with scattering angle.
