What is laser diffraction?

Laser diffraction has become the main light scattering technique for particle size distribution analysis, with applications ranging from nanometer to millimeter levels. This versatile technique involves passing a laser beam through a sample dispersed as a liquid suspension or dry powder and then analyzing the resulting scattering pattern, with the diffraction angle indicating particle size.

The technology enables real-time monitoring and control of dispersions, high sample throughput, and hundreds of analyzes per day. Additionally, the technology does not require calibration and its accuracy can be verified at any time using standard reference materials.

Laser diffraction combines the advantages of simple operation, fast measurement, ruggedness and repeatable high-resolution particle size analysis with a wide dynamic range and orders of magnitude, making it the most important particle characterization technology in a variety of applications.
