摘要： An immersion projection optical system having, for example, a catadioptric and off-axis structure, reduces the portion of an image space filled with liquid (immersion liquid). The projection optical system, which projects a reduced image of a first plane onto a second plane through the liquid, includes a refractive optical element (Lp) arranged nearest to the second plane. The refractive optical element includes a light emitting surface (Lpb) shaped to be substantially symmetric with respect to two axial directions (XY-axes) perpendicular to each other on the second plane. The light emitting surface has a central axis (Lpba) that substantially coincides with a central axis (40a) of a circle (40) corresponding to a circumference of a light entering surface (Lpa) of the refractive optical element. The central axis of the light emitting surface is decentered in one of the two axial directions (Y-axis) from an optical axis (AX).

摘要： There is provided a projection optical system preferable for reducing the depth and a lower portion (or upper portion) of a screen of a rear projection television which has a low distortion, a high resolution, a reduced refection area, and a reduced number of reflection surfaces. The projection optical system enlarges/projects from the primary image surface of the reduction side to the secondary image surface of the enlargement side. The projection optical system includes a first optical system (L11) for forming an intermediate image (position II) of the primary image surface and a second optical system (L12) having a concave reflection surface (AM1) for forming the secondary image surface by the intermediate image. The light ray passing from the center of the primary image surface to the center of the secondary image surface intersects the optical axis and is further reflected by the concave reflection surface to again intersect the optical axis and reach the secondary image surface.

摘要： An optical system includes a reflecting mirror to which rays are incident across a relatively wide incidence angle range, while well suppressing a change in a polarization state in an optical path of a beam incident substantially as linearly polarized light. The optical system has a first deflecting plane mirror (M11) and a second deflecting plane mirror (M12) and a substantially linearly polarized beam is incident to the optical system. Each of the first deflecting plane mirror and the second deflecting plane mirror is so arranged that a change from a phase difference between p-polarized incident light to a reflecting surface and s-polarized incident light to the reflecting surface, to a phase difference between reflected light of the p-polarized incident light to the reflecting surface and reflected light of the s-polarized incident light to the reflecting surface is within 30° for all rays incident to the reflecting surface.
