The Polydisperse Particle Standards were formally known as the BCR 'Mirror' Standards because they mirrored the size ranges of an official set of spherical reference standards that were being developed for the European Community (Community Bureau of Reference - BCR).
Most particle size reference standards are transparent in nature including glass and latex microspheres However in some optically based particle
