摘要：Apparatus () for measuring the particle-size distribution of a sample by light-scattering comprises a focusing optic () for producing a converging beam () generally
along a propagation axis z. The apparatus comprises a mounting system which allows adry sample cell (A) and a wet sample cell (B) to be mounted in the converging beam atdifferent times and in respective planes which are mutually inclined so that in use of theapparatus respective positions () at which transmitted light is focused for the two cellshave a difference in displacement from the z axis that is less than for the case where therespective planes are substantially parallel. This allows use of a cheaper and lesscomplex translation stage within the apparatus for mounting an optical detector forlocating the two focus positions.
