ABSTRACT:
A three-dimensional image observation microscope system includes an imaging unit that captures images focused at different object point distances in an optical axis direction and a display unit that displays a plurality of the images captured by the imaging unit for overlaid observation along the line of sight of a viewer as a three-dimensional image. The imaging unit includes an objective optical system that obtains an image of an object, a zoom optical system that controls the magnification of the image obtained by the objective optical system, and a plurality of image pickup devices that capture the images with a magnification controlled by the zoom optical system. Specified conditions related to focal length, numerical apertures, inclinations, magnifications and distances within the imaging unit and the display unit are satisfied.
