The zoom lens includes a first reflection plate and a second reflection plate having reflection surfaces facing each other; a light incidence region disposed around the second reflection plate; a light exit region disposed in a hole in a center portion of the first reflection plate; and a mirror, which is disposed around the second reflection plate and reflects light incident via the light incidence region toward the first reflection plate. The mirror is configured to change a length of a an optical path of light incident via the light incidence region, reflected between the first reflection plate and the second reflection plate, and exiting the zoom lens via the light exit region.
