The Microtrac S3500 is a industry-preferred Laser Diffraction (LD) analyzer, ideally suited for various particle characterization tasks. It is the first particle size analyzer that uses three precisely placed red laser diodes to accurately characterize particles like never before. The patented Tri-Laser System provides accurate, reliable and repeatable particle size analysis for a diverse range of applications by utilizing the proven theory of Mie compensation for spherical particles and the proprietary principle of Modified Mie calculations for non-spherical particles. The S3500 measures particle size from 0.02 to 2,800 µm.Laser Diffraction with red and blue lasers: BLUEWAVE
