Abstract
An illuminating apparatus for a microscope comprises a housing having an opening for passing light through. To this end there is at least one electrical light source in the housing arranged to direct at least one light beam through this opening. There are means for preventing an electrical discharge within the range of the opening and are selected from shielding means and conductive discharge means. Preferably, prevention is effected by a cover for covering the opening and permitting the light beam to penetrate it. This cover means is electrically conductive at least in part and comprises a transparent plate element having at least one surface extending over the opening and including an electrically conductive coating connected to earth potential.
