Abstract

See full text

An axially symmetric polarization conversion element that converts incident light into an axially symmetric polarized beam includes a reflection section having a shape obtained by rotating the cross section of a Fresnel rhomb wave plate along the direction of an optical axis around an axis that is parallel to the optical axis. The axially symmetric polarization conversion element converts the incident light into an axially symmetric polarized beam by utilizing two Fresnel reflections by the reflection section.
