ABSTRACT:
Illuminating apparatus for a microscope including a semitransparent, in picular dichroic, microscope mirror for reflecting illuminating light from an external illuminating unit into a microscope beam path. The illuminating unit comprises a coupling-in unit having a first beam path which leads from a light exit end of a first optical waveguide through a semitransparent coupling-in mirror and an adapter optical system to the microscope mirror, furthermore, a second beam path which leads from a light exit end of a second optical waveguide via the semitransparent coupling-in mirror operating in reflection and the adapter optical system to the microscopic mirror, a first light source unit which is optically coupled to a light entrance end of the first optical waveguide and a second light source unit for flashlight which is optically coupled to a light entrance end of the second optical waveguide.
