Airborne Particle Counter for Aerospace
Aerospace application: Portable airborne-particle measurement for cleanroom verification, reporting, and point-of-use investigation.
Airborne particles scatter light when illuminated, a phenomenon known as light scattering. Scattering depends on particle size, light wavelength, particle refractive index, and the light absorption characteristics of the particles. For scattered-light intensity and particle size, particle counters follow a basic principle: the intensity of light scattered by a particle increases as its surface area increases. Measuring scattered-light intensity therefore allows particle size to be inferred. This is the basic operating principle of a light-scattering particle counter.
