Abstract

PURPOSE:To obtain a two-dimensional sample and to obtain detailed information by obtaining the fluorescent image from a preliminarily fluorescent-dyed sample by another magnifying lens on a photodetector. CONSTITUTION:A laser beam diameter of a laser luminous flux 2 from a laser 1 of a cell analyzing instrument 1 is magnified by lenses 3, 4 and is made into parallel luminous fluxes which are condensed by a light lens 5 of a short focal length. The lens 5 is attached to a bimorph oscillator consisting of two sheets of piezo-electric elements and the oscillator 6 is fixed by a fixing jig 7. The condensed laser beam is controlled by an oscillator driving circuit 12 in such a manner that a beam west comes near to the center of a transparent glass cell 8 in which an observation sample such as cells is allowed to flow. The sample to be passed in the cell 8 is preliminarily subjected to fluorescent dyeing to emit fluorescence by absorbing laser light. The fluorescent image is projected by an objective lens 9 onto a one-dimensional image sensor 10. The two-dimensional sample is obtd. by moving the sample by which the detailed information on the cells, etc., is obtd.
