ABSTRACT OF THE DISCLOSURE: A K?hler illuminating device for microscopes, comprising a light guide serving as a uniform increased- area source of secondary light. The light guide includes a bundle of glass fibers having an exit end, and a glass body engaged against the end for receiving light trans- mitted through the bundle and for producing a substantially uniform luminous density distribution at a light exit sur- face of said glass body, a housing containing the glass body and the exit end of the bundle. An aperture diaphragm is provided in the housing in the immediate vicinity of the light exit surface of the glass body to control the aperture of a light beam issuing therefrom. An illuminating field diaphragm is also provided in the housing in the path of light passing the aperture diaphragm. A collector is located in the path of light between the aperture diaphragm and the illuminating field diaphragm. Means are provided for attaching the housing selectively as desired, either on a microscope arm of a reflected-light microscope, in posi- tion to illuminate a specimen by reflected light, or to a holder of a condenser of a transmitted-light microscope, in position to illuminate a specimen by transmitted light.
