Abstract: In order to be suited for long-term use in an enclosed space and to enable various modes of illumination by simple procedures and at a low cost without adding special optical components, the illuminating device for microscopes of the invention comprises a surface light source including a plural number of semiconductor light sources arranged in two dimensions, a control circuit selectively lighting some or all of the plural number of semiconductor light sources in conjunction with selection of an illumination mode, and an optical system for condensing and transmitting the light from the surface light source. The illuminating device of the invention makes it possible to observe a sample simultaneously in different illumination modes when the illuminating device is equipped with three surface light sources and the sample is irradiated simultaneously with the lights from the three surface light sources.
