[A method and device for measuring the levels of microscopic objects in suspension]

The major drawback of the routine methods for measuring the suspension concentrations with a microscope is the predominance of the examined area where the particles are concentrated beyond the microscope visual field. To make the examination more convenient, short, and accurate, it is recommended that the suspension particles contained in a certain volume be concentrated with the use of a camera, shaping them as a truncated cone on its smaller foot, equal to a single visual field of the microscope, and there these particles be scintillated.
