Due to relatively recent advances in theory, light transmission apparatus need not be calibrated against monodisperse standards in order to provide accurate size information for transparent spherical particles. However, the precision of construction necessary for accurate results has not heretofore been evaluated. In this paper the effects of unavoidable approximations in the optical construction of light transmission apparatus are evaluated quantitatively. Tables and graphs are presented which will enable the apparatus designer and user to avoid, or at least account for, errors in interpretation of light transmission data, without resort to empirical calibration. |
