摘要： This invention provides a microscope for operation which can form a black point for protecting a patient's retina even when the retina part is not at the center of the field of view of the microscope. The microscope for operation has an X-Y stage for moving the microscope body, a CCD camera for obtaining an image in the field of view of the microscope, a liquid crystal device provided with a light transmitting surface transmitting illuminating light therethrough and comprised of display dots disposed in the form of a matrix, and a control device for controlling and driving the liquid crystal device. The control device analyzes the image in the field of view of the microscope obtained by the CCD camera to thereby recognize the position of the retina part of an eye to be examined, and the display dots positioned in that area on the light transmitting surface of the liquid crystal device which has been determined correspondingly to the recognized position are selectively colored to thereby constitute a black point filter.

摘要： An ophthalmic photographing apparatus comprises an illumination optical system for illuminating an eye to be tested, a viewing optical system having a variable magnification optical system for viewing the illuminated eye to be tested, and a photographing device detachably mounted on the viewing optical system. A position change of a predetermined part due to the change of magnification of the variable magnification optical system is measured to produce a signal representing the displacement. The signal representing the magnification of the variable magnification optical system is used to control an intensity of a flash light.

摘要： A microscope includes an objective lens and 1st, 2nd, 3rd and 4th magnification-varying optical systems of a same power, having optical axes parallel to the optical axis of the objective lens and positioned behind the objective lens and around the optical axis thereof. An objective unit houses the objective lens and the 1st, 2nd, 3rd and 4th magnification-varying optical systems. A deflection optical system directs two specified light beams, among the light beams transmitted by the 1st, 2nd, 3rd and 4th magnification-varying optical systems, to a first direction and also directs the remaining two light beams to a second direction. A first observation optical system respectively forms images, for observation, by the two light beams directed to the first direction. A second observation optical system respectively forms images, for observation, by the two light beams directed to the second direction. First and second observation units are detachably mountable alternatively to the objective unit. The first observation unit is provided with the deflection optical system and the first observation optical system, while the second observation unit is provided with the deflection optical system and the second observation optical system. The deflection optical system in the first observation unit is so constructed that the first and second directions form a predetermined first angle, and the deflection optical system in the second observation unit is so constructed that the first and second directions form a predetermined second angle different from the predetermined first angle.
