Particle Analyzer
HORIBA LA-300
The LA-300 operates on the basis of static laser light scattering and covers a wide range of applications. It is the ideal combination of performance, price and packaging.
The diode laser is capable of detecting particles with the highest precision and resolution in a very short time (approx. 10 s.). The wide measuring range from 0.1 - 600 µm makes it the ideal analyzer for applications in basic research and quality control.
The LA-300 strikes a harmonious balance between high-functionality, easy operation, low maintenance, and cost-effectiveness.

Function Principle
The LA-300 uses Mie Scattering Theory (laser diffraction) to measure particle size over the range of 0.1 to 600 µm. A 650 nm solid-state, diode laser is focused by an automatic alignment system through the measurement cell. Light is scattered by the particles to a 42-element detector system, including high-angle and back-scatter detectors for a full angular light intensity distribution. The thick, cast-aluminum optical bench provides stable, high-precision results. For more information on the technology behind all that, visit our "Technical basics" page.
