The operating microscope is one of the most important instruments in modern neurosurgery. The history and technical aspects of the microscope have been discussed in many papers; here I would just briefly stress five important properties which the instrument must possess for neurosurgical application (1) The objects can be seen clearly and sharply through the lens system. (2) Illumination is strong and the illuminated field wide. Multiple sources of illumination are especially useful in neurosurgical applications because one beam may sometimes be obstructed in a deep and narrow field by a bone edge or other object. (3) Rotation and tilting of the microscope body can be performed easily and quickly. (4) Vertical shifting can be done at two different speeds: fast and slow. (5) Accessory systems can be implemented easily when needed.
