LS Spectrometer™

Dynamic and static light scattering for powerful particle characterization

The LS Spectrometer™ is a goniometer-based multi-angle static light scattering (SLS) and dynamic light scattering (DLS) instrument for particle characterization. It is a modular platform enabling a high degree of customization. Even in its basic configuration, the LS Spectrometer™ is one of the most sophisticated instruments on the market and is particularly well suited as an entry-model. Should your demands on the device increase over time, the LS Spectrometer™ can easily be upgraded to the 3D LS Spectrometer™ configuration at any time. Our patented modulated 3D Cross-Correlation technology opens up the world of error-free particle characterization of even highly concentrated samples.
