Introduction to laser diffraction

This e-learning training provides a comprehensive introduction to laser diffraction particle size analysis and the fundamental principles behind the technique. The course is designed for scientists, engineers, laboratory analysts, and anyone interested in understanding how laser diffraction measurements are performed, optimized, and interpreted.

Throughout this masterclass, learners will explore the fundamentals of light scattering, optical models, method development, sampling and dispersion techniques, data interpretation, and specification setting. The course also introduces key industry standards and best practices used to ensure reliable and reproducible particle size measurements.

Topics covered include:

• Fundamentals of laser diffraction theory
• Mie Theory and Fraunhofer optical models
• Wet and dry dispersion methods
• Sampling and method development
• Repeatability, reproducibility, and robustness
• Particle size distributions and reporting
• ISO 13320 and industry standards
• Specification setting and measurement precision

This training can be completed at your own pace. You may start, pause, and resume the course at any time until all lessons are complete. Each lesson is followed by a short knowledge assessment, and the course concludes with a final quiz.

By the end of this course, you will be able to:

• Understand the principles of laser diffraction particle sizing
• Explain how light scattering relates to particle size
• Differentiate between Mie Theory and Fraunhofer approximation
• Develop suitable wet and dry dispersion methods
• Identify key factors affecting measurement quality and repeatability
• Interpret particle size distributions and reporting metrics
• Understand how particle size specifications relate to product performance
• Apply industry best practices for laser diffraction measurements

Upon successful completion, you may print your certificate.
