<p>Laser light from the laser light source (14) is conveyed by means of the laser light conveying device (40) to the collimator. After being collimated the laser light is transmitted to the first focusing device (64) whereby the laser light is focused and is then made to pass across the sample path (74). The laser light is scattered by the particles that are present in the sample path (74). Both scattered and collimated light is collected by the second focusing device (78) and then focused thereby on to the detector device (82) such that the intensity distribution of the laser light is gathered by the detector device (82). Particle size distribution is inferred from the light distribution received by the detector device (82).</p> |
