Abstract:
1. An analyzation instrument, comprising: a) a flow source to produce a flow of particles through an inspection zone; b) a source of electromagnetic radiation adapted to direct electromagnetic radiation onto said flow of particles at said inspection zone; c) a partial ellipsoidal collector having a near focal point at said inspection zone and a distant focal point which define an optical axis along a line between said near focal point and said distant focal point, said flow of particles substantially aligned with said optical axis, said electromagnetic radiation either produced or deflected from said flow of particles reflected from said partial ellipsoidal collector converges towards said distant focal point; and d) a sensor which senses said electromagnetic radiation which converges towards said distant focal point; e) a processor which processes sensed electromagnetic radiation to derive predetermined information of particles; and f) a sorting apparatus to sort said particles based on said predetermined information downstream of said flow source.
