Vessel for imaging fluorescent particles

摘要

A vessel for containing fluorescent particles that are to be imaged is proposed. The fluorescent particles are stained with a fluorescent dye, collected in the bottom portion (3') of the vessel (3) and illuminated from below by a beam of excitation light (1). Part of the exterior surface of the bottom portion is an excitation light entry surface (3e). Thus, with only the bottom portion (3') or the vicinity thereof being illuminated, background light is reduced, thereby improving the contrast of the images of the particles. <IMAGE>
