    摘要: A surgical microscope system having a stereoscopic optical system, an imaging unit, and a monitor display. The stereoscopic optical system has two optical paths and forms a 3D image of an object. The imaging unit forms two images of the object from two light beams focused in the optical paths. The monitor display displays the images of the object which the imaging unit has formed. The surgical microscope system further comprises an observation-light receiving section located in the optical paths for determining an observation field, an observation-light emitting section located in the monitor display for applying the images formed by the imaging unit, and reflectors arranged between the observation-light receiving section and the observation-light emitting section. The observation-light receiving and the observation-light emitting sections are located close to each other and a barrel holds the sections together. Images displayed on the monitor display are projected such that the observer perceives a 3-dimensional virtual image located at a distance from the observer equal to the actual distance between the observer and the object.

    摘要: An imaging apparatus is provided with a negative lens, a variable focal length lens unit including a material with an electrooptic effect, a light blocking unit, including the material with the electrooptic effect, capable of changing an aperture diameter, and a switch, interlocked with each other, capable of supplying electric power to the variable focal length lens unit and the light blocking unit which are arranged in order on an optical axis from an object side to an image side. When the switch is turned off, the variable focal length lens unit is set to bring an object at a far point into focus and the light blocking unit is set so that an aperture is determined by an aperture stop, while on the other hand, when the switch is turned on, the variable focal length lens unit is set so that an object at a near point is in focus and the light blocking unit is set to be smaller in aperture. Apertures different in size are determined by a plurality of annular transparent electrodes incorporated in the light blocking unit and configured concentrically. Thus the imaging apparatus can be constructed to be small or compact in size and is easy in manufacturing.
