Abstract
A detection optical system includes an objective lens, a first relay lens, a second relay lens, and an imaging lens, which are arranged in order from a side of a specimen along an optical path of light from the specimen illuminated by a light source. A primary imaging plane is provided on the optical path between the first relay lens and the second relay lens. An aspherical correction plate that corrects spherical aberration is arranged at a position located between the second relay lens and the imaging lens and substantially conjugate with a pupil position of the objective lens.
