Abstract
Provided is an optical device, comprising a plurality of polarizers that are arranged along a propagation direction of incident light; a first phase element that is disposed between the plurality of polarizers and that has a phase lag axis forming a prescribed angle relative to transmission axes of the polarizers arranged along the propagation direction; and a second phase element that is disposed between the first phase element and one of the polarizers arranged along the propagation direction, and that provides the incident light with a prescribed phase difference. An angle of the phase lag axis of the second phase element is adjusted such that the optical device transmits light in a prescribed wavelength region in the incident light.
