Particle Size Determination and the Importance of Optical Properties in Accurate Measurement

Accurate particle size measurement is essential for quality, performance, and safety across multiple industries — from pharmaceuticals and energy storage to materials manufacturing. In this whitepaper, DEKRA Organisational and Process Safety explores how optical properties such as refractive index and absorption significantly influence the accuracy of particle size determination using laser diffraction. Through detailed analysis and data examples, the paper illustrates how using incorrect optical parameters can distort results, impact process efficiency, and lead to costly errors in research and production. Readers will gain a deeper understanding of Mie and Fraunhofer scattering models, practical guidance on ensuring measurement reliability, and the importance of precision in optical data for maintaining quality control and regulatory compliance.
