The future of particle characterization

Holographic particle tracking

Holographic particle tracking can identify different particle types in liquids based on their refractive index and/or shape. By tracking each particle individually and determining its optical properties as well as its movement we can characterize particle dispersions in unprecedented detail.

How it is used

Analysis of particles in liquids is of great importance in many fields, ranging from life science to water analysis.

How it works

When highly ordered laser light passes through the sample, it collects detailed information which is extracted digitally using advanced image processing and machine learning.
