Abstract:
1. A microscope optical system comprising: an objective lens to be located nearest to a sample in an optical path between the sample and an image to be observed; a variable magnification optical system that forms an intermediate image conjugate with the sample, together with the objective lens; a mirror having a reflecting surface disposed in the optical path between the objective lens and the variable magnification optical system, the mirror being arranged to change position of the reflecting surface by tilting of the mirror so as to change a direction of the optical path; a mirror controller that controls the tilting of the mirror; a micromanipulator that manipulates the sample; a manipulator controller that controls movement of the micromanipulator; and a computer operatively connected to the mirror controller and the manipulator controller, wherein the computer instructs the mirror controller to tilt the mirror and simultaneously therewith determines a direction and an amount of the displacement of the observation field of view based on an angle of the tilt of the mirror, and instructs the manipulator controller to change a position of said micromanipulator based on the determined direction and the amount of the displacement of the observation field of view.
