Abstract
An observation device where a first light path in an illumination optical system is different from a second light path in an object optical system, the illumination optical system includes a light source that emits the illumination light in a first direction, and an illumination deflector that deflects the illumination light from the first direction to a second direction, a pre-reflected illumination angle between a pedestal surface holding the sample and the first direction is smaller than a post-reflected illumination angle between the pedestal surface and the second direction, the object optical system includes a transmission deflector that deflects the transmission light transmitted through the sample from a third direction to a fourth direction, and a post-reflected transmission angle between the pedestal surface and the fourth direction is smaller than a pre-reflected transmission angle between the pedestal surface and the third direction.
