Abstract

An observation device capable of observing a first image formed by an objective optical system, includes: a display element into which an illumination light emitted from an illumination source is incident and that generates a second image with the illumination light to superimpose the second image over the first image formed by the objective optical system; a detector that receives the second image to detect information of the second image; and a filter that filters out light of the illumination light advancing to the detector.
