Abstract
An optical system includes: a first optical member having a concave surface that reflects a light having a first circularly polarized light component and transmits a light having a second circularly polarized light component a rotation direction of which is opposite to a rotation direction of the first circularly polarized light component; and a second optical member that transforms the light having the first circularly polarized light component reflected from the first optical member into the light having the second circularly polarized light component to be reflected so as to be incident on the first optical member.
