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
