Abstract: The inventive optical spherical lens light scattering apparatus and method for use thereof comprises an incident light source, a spherical or ball optical lens system and a photo detector. The spherical or ball lens optical system comprises at least one ball or spherical lens being in contact with a specimen of fluid dispersed particles; said ball lens having, as a result of its spherical geometry, and as compared to a plano-convex or convex lens, a relatively short focal point. When the incident light source is used to generate a beam of light, and the beam of light is then focused through the spherical or ball lens, it lands at a point that is much closer to the lens, as compared to the point it normally lands on, when it is focused through a plano-convex, or a convex lens.
