Reflection type projector including a sheet polarization beam splitter and a correction mechanism which corrects an aberration of the incident light caused by the sheet polarization beam splitter

Abstract

A reflection type projector having a structure so that aberration generated when sheet type PBS is adopted is corrected is provided. The reflection type projector includes a light source, a sheet type PBS arranged to be inclined with respect to an optical axis on a proceeding path of light emitted from the light source, a reflection type display device for generating an image from an incident light polarized in one direction passing the sheet type PBS and reflecting the generated image toward the sheet type PBS, a relay lens unit arranged on an optical path for guiding an incident light by focusing and/or diverging the incident light, a device for correcting aberration of an incident light, arranged on a proceeding path of the light generated from the reflection type display device and passing the sheet type PBS, and a projection lens unit for magnifying and projecting the light transmitting the correction device toward a screen.
