Abstract
Transmissometers always accept a certain portion of the forward-scatte red light. The error in the beam-attenuation coefficient c(lambda) due to this acceptance varies with the small-angle scattering function, s ingle-scattering albedo, and instrumental design. This paper details m ethods to model error in measurements of c(lambda) obtained with cylin drically limited and collimated-beam transmissometers. These models ar e used with real examples of beam attenuation and small-angle scatteri ng function data to test how this measurement error varies.
