<<< Previous --- Next >>>

Measurements at 2 scattering angles (field of view of few degrees) :

~12°, insensitive to the refractive index of the particles (mainly diffraction)

   => accurate size determination and counting

~60°, strongly sensitive to the refractive index of the particles

   => indication of the typology of the particles

Detection of the maximum of intensity for particle that crosses the laser beam

Real-time stray light correction
