Abstract

An observation apparatus includes a case having a transmissive window, an image sensor, an optical system, and a light source housed in the case, and an optical deflection unit. The optical system is configured to condense light incident inside the case to form an image of a sample inside a container. The light source is configured to emit light to the outside of the case without passing through the optical system. The optical deflection unit is configured to deflect light emitted to the outside of the case from the light source to a first direction proceeding toward the transmissive window. An angle of exit between the first direction and an optical axis of the optical system is different from an angle of incidence between a second direction in which light emitted to the outside of the case is incident on the optical deflection unit, and the optical axis.
