Abstract
An apparatus designed to measure the optical constants of a powder suspended in a liquid is described. A laser source (3.391 µm) and attenuated total reflection approach are used. The accuracy of the apparatus is evaluated by comparing measured results for a liquid hydrocarbon with published results obtained using a different technique. An error analysis is presented. Data obtained for a carbon black powder are discussed and compared with previously published results from specular reflection measurements. The applicability of the Maxwell-Garnett effective medium theory is considered.
