Abstract

PURPOSE: To realize manifold illumination and easy space coherence control by employing such constitution that the light source of the illumination system of an optical microscope is formed in a LED array, and the shape itself of the light source can be changed by light control.
CONSTITUTION: The light source of the illumination system is comprised of high luminance light emitting diodes 2 on each of which the light control can be applied independently, and it is arranged on the front side focal point plane of a condenser lens 4. The illumination strength can be controlled by the number of light of light emitting diodes 1, and also, the shape of the light source itself is changed by selecting the pattern of the light emitting diode to be lit, thereby, zonal illumination, oblique illumination, and dark field illumination can be performed. In such a way, the miniaturization and light weight of a chemical microscope can be attained, and also, the manifold illumination i.e. a various kinds of space coherence control can be easily and quickly performed.
