Abstract
A microscope for operation having an illuminating optical system for illuminating an illuminating light toward an eye to be operated upon, an objective body tube with an objective positioned in the body tube to be opposite to the eye, a pair of observing optical systems disposed at opposite sides of an optical axis of the objective for observing the eye, a front lens disposed between the objective and the eye to collect the illuminating light and to guide the collected light in the front of the eye for illuminating the interior of the eye, and a slit plate provided in the optical path of the illuminating optical system.
Claims7
A microscope for operation comprising:
- an illuminating optical system for illuminating an illuminating light toward an eye to be operated upon;
- an objective body tube;
- an objective provided in said objective body tube to be opposite to said eye;
- a pair of observing optical systems disposed at opposite sides of an optical axis of said objective for observing said eye;
- and
- a front lens disposed between said objective and said eye to collect said illuminating light and to guide the collected light in a front of said eye for illuminating an interior of said eye;
- and
- a slit plate provided in an optical path of the illuminating optical system.

- and
- a front lens disposed between said objective and said eye to collect said illuminating light and to guide the collected light in a front of said eye for illuminating an interior of said eye,
- said illuminating optical system being provided with a slit plate having a slit hole for converting the illuminating light into a slit illuminating light, said slit hole extending in a direction vertical to an optical axis of said illuminating optical system,
- an image of said slit hole focused on a fundus of said eye being parallel to a plane including both axes of said observing optical systems, said slit plate being movable in a direction vertical to an optical axis of the illuminating optical system for moving said slit illuminating light to approach to and separate from said optical axis of said objective.
