OPTICAL ELEMENT AND OPTICAL SYSTEM

摘要

An optical element (10A) according to an embodiment of the present invention has: a first main surface onto which light emitted by an object being projected is incident; a second main surface parallel to the first main surface; a reflective image-forming element (11) having two mirror surface elements (14a, 14b) that are perpendicular to the first main surface and orthogonal to each other; and a polarizing plate (22a) disposed on the second main surface side of the reflected image-forming element (11).
