Abstract
Provided is an optical structure in which an alignment compensator is disposed at a rear stage of a polarizing beam splitter, and when a first input light having a first wavelength (λ1) is input to the polarizing beam splitter and when a second input light having a second wavelength (λ2) is input to the polarizing beam splitter, the alignment compensator is set such that, on a light outgoing plane of the alignment compensator, a traveling direction and an outgoing position of ordinary light of the first input light and a traveling direction and an outgoing position of ordinary light of the second input light coincide with each other, and a traveling directions and an outgoing position of extraordinary light of the first input light and a traveling direction and an outgoing position of extraordinary light of the second input light coincide with each other.
