Abstract
An illumination device for a microscope, in particular for an operation microscope, has a light source with an improved lifetime. The light source is in the form of a gas discharge lamp having a microwave generator, a microwave waveguide and an electrodeless bulb. The bulb contains a luminescent material and is coupled to the microwave waveguide so that microwaves can stimulate the luminescent material to emit light.
