Abstract
A microscope illumination apparatus, which has at least three kinds of light sources, each of a different emission wavelength region and a different figure and size of the light-emitting section, and supplies emitted light from individual light sources as illumination light for observing a specimen to the microscope body, includes collimator lenses converting incident rays into parallel rays, arranged on the exit sides of the individual light sources; a path sharing means introducing light emerging from the collimator lenses into a common optical path; an imaging lens, placed on the common optical path, forming images of the individual light sources introduced into the common optical path through the path sharing means at a common position; and an optical fiber placed so that the entrance end face of the optical fiber is located at a position where the images of the individual light sources are formed through the imaging lens.
