Abstract
A surgical operation microscope has an observing optical system for observing an eye through an objective lens, and an illuminating optical system for illuminating the eye. The illuminating optical system includes a display element disposed in a position generally conjugate to an observing surface of the eye and adapted to display an image of information required for a surgical operation. The image of information on the display element is projected to the observing surface by an illuminating light source of the illuminating optical system.
