摘要
The invention concerns an illuminating device for an optical magnifying instrument (1), in particular a magnifying glass, a diagnostic microscope or a surgical microscope, comprising a lens (2) designed to represent the light of an object to be analyzed, and a field (5) of light emitting diodes (4), said light emitting diodes being arranged on the surface of the lens (2) which is not facing the object and emitting a radiation through the lens (2) in an axial direction (A) which is parallel to the direction of observation (B). The invention is characterized in that said field (5) includes at least one through aperture (6a; 6b) extending in the axial direction (A), delimiting the observer's visual field and around which are arranged said light emitting diodes (4). The invention further concerns an optical magnifying instrument (1), in particular a magnifying glass, a diagnostic microscope or a surgical microscope, which can be used on a wall or a covering structure and installed on a table or a tripod. Said optical magnifying instrument comprises an illuminating device, a powering unit for said illuminating device, and an eyepiece tube (3). The invention is characterized in that said illuminating device is such as defined above and the field (5) of light emitting diodes (4) is arranged between the lens (2) and said eyepiece tube (3).
