Abstract

A microscope includes an objective optical system including an imaging optical system configured to form an image of an object, a re-imaging optical system configured to re-form an image of the object image formed by the imaging optical system, and a reflection unit arranged on an optical path between the imaging optical system and the re-imaging optical system and configured to be locally changeable in at least one of a position thereof in an optical axis direction and an inclination thereof relative to an optical axis, and an image sensor configured to capture the image re-formed by the objective optical system.

Description

technical field [0001] The present invention relates to an objective optical system of an image acquisition device (for example, a microscope) suitably used for acquiring image data of, for example, a pathological sample. Background technique [0002] In pathological examinations in recent years, attention has been drawn to an image acquisition system that captures an image of a pathological sample using an image acquisition device (for example, a microscope) to acquire image data and displays the acquired image data on a display to allow a human to observe the displayed image data. The image acquisition system enables multiple people to simultaneously observe image data acquired by imaging a sample and share the image data with a remote pathologist. [0003] If a large sample that does not fall within the field of view of the objective lens is observed in the image acquisition device, image data representing the entire sample needs to be acquired by either moving the sampl...
