Abstract
A relay system brings a beam output from a first image plane into focus at a second image plane. The relay system includes a first lens element, a reflection member, and a second lens element sequentially arranged in the direction in which the beam travels. The first lens element has positive power. The reflection member has a transmissive surface that is a concave surface on which the beam is incident and via which the beam exits, and a reflective surface that is a concave surface that reflects the beam from the transmissive surface. The second lens element has positive power. The beam output from the reflection member passes through the second lens element and is brought into focus at the second image plane.
