Abstract: An illumination system is provided for a single objective lens-type binocular microscope. The arrangement features a slot cut in a single objective lens. A prism is inserted into this slot. An illuminating light flux is conducted to the prism at an axis different from the axis of observation through the objective lens. The prism conducts this light to the axis of observation so as to illuminate the area to be observed. Thus, the angle between the illuminating light flux and observing light flux can be made extremely small permitting the deep illumination of the area to be observed.

Abstract: Provided is an operation microscope apparatus for easily and speedily obtaining a suitable separation state between illumination light and observation light in a case where a front lens is replaced by another one. An illumination optical system includes a slit plate in which slit holes having different slit widths are formed. Each of a plurality of front lens having different refractive powers is integrally formed with corresponding one of storing sections. One of the storing sections is attached to an elevation regulating member. The elevation regulating member includes micro-switches. Each of the storing sections includes a protruding portion for turning on corresponding one of the micro-switches at the time of attachment. A control unit sets an illumination angle of the illumination light and a slit width of a slit based on a detection signal from a micro-switch which becomes an on state.

Abstract: Disclosed is an observation apparatus capable of eliminating in a suitable manner astigmatism and chromatic aberration generated in an observed image. The apex angle θ of a contact prism is input by operating an apex angle setting knob of a control panel, and the attachment angle thereof is input by operating an attachment angle setting knob. Based on the observation magnification recognized and the input apex angle θ, a control device determines the astigmatism correction amount for a left observation optical system and determines the astigmatism correction amount for the right observation optical system. Further, based on the input attachment angle, the axial angles of the astigmatisms of the left observation optical system and the right observation optical system are determined. Next, variable cross cylinder lens rotation drive devices are respectively controlled to rotate the respective cylinder lenses of the left and right observation optical systems to achieve the axial angle and correction amount as determined.

Abstract: There are provided an operation microscope and an observation prism which are capable of conducting a high-visibility observation with less glare. The operation microscope includes an objective lens opposed to an eye to be operated, a front lens which is provided between the eye to be operated and an anterior focal point of the objective lens and condenses illumination light to illuminate an interior of the eye to be operated, and the observation prism disposed near the front lens to observe fundus and its surroundings of the eye to be operated. An oblique surface (refractive surface) of the observation prism has a curved shape in which the curved shape shows a certain negative curvature in a direction to an intersection with a refractive surface. Therefore, aberrations caused on images of entrance pupils of an observation system and an image of an exit pupil of an illumination system can be corrected. The images of the entrance pupils and the image of the exit pupil are sufficiently separated from one another on a cornea of the eye to be operated, so that an observation with less glare can be conducted.
