Abstract: A surgical microscope system (1, 2, 3, 4, 5, 6) having a display (7a-7e). Data essential for the surgical procedure, for example video images, are displayed in the observer's immediate field of view, thus making it unnecessary to turn one's head away from the surgical visual field. Because of its optical properties, the display (7a-7e) can also be attached, for example, on the curved exterior of the microscope body (2) or also on an X-Y coupling (6) that may be present. An rigid OLED display or a flexible OLED display is preferably used.
