摘要： A projection optical system includes first and second optical systems. The first optical system includes a transmissive-refractive element and the second optical system includes a reflective-refractive element. An image formed by a spatial light modulator is projected by the projection optical system on a projection surface. A light beam that travels along an optical path that leads from the second optical system to the projection surface in an optical path between a center of the image formed by the spatial light modulator and the projection surface is projected at an angle with respect to a normal to the projection surface. An optical axis of the first optical system is folded to a folded position by an optical path deflecting unit in an area of the first optical system where the light beam entering the optical path deflecting unit is a converging light beam or a substantially parallel light beam.

摘要： Disclosed are a projection display apparatus and a projection optics provided in the projection display apparatus. The projection optics has a refractive optics and a reflective optics. In the refractive optics, a lens (non-circular lens) provided on a reflective optics side has a non-circular shape forming part of an imaginary circular region whose center is an optical axis center of the refractive optics. In other words, the non-circular lens has a shape of a cut-out portion of an imaginary circular lens having an optical axis center coinciding with the optical axis center of the refractive optics.

摘要： A projection optical system includes a first refracting optical system having a plurality of lenses, a first reflecting optical system, and a second reflecting optical system. The first reflecting optical system is disposed on a side of a projection port with respect to an optical axis of the first refracting optical system, and has a positive optical power to reflect light incident through the first refracting optical system in a direction opposite to the side of the projection port. The second reflecting optical system is operable to reflect the light reflected on the first reflecting optical system toward the projection port.
