摘要： A projection optical apparatus capable of providing high image quality and having a reduced size is disclosed. The projection optical apparatus includes a light valve and a projection optical system including a first optical system having a transmissive-refractive element and a second optical system having a reflective-refractive element. An image formed on the light valve is projected by the projection optical system on a projection surface. The optical axis in the first optical system is folded both vertically and horizontally. The first group of the first optical system is contained in a space (dead space) whose lower limit is defined by a lower edge of the second optical system, thereby reducing the depth of the apparatus.

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.

摘要： An illumination apparatus includes a reflector including a parabolic or ellipsoidal mirror, a light source arranged near a (first) focal point of the reflector, and a front mirror having a transparent window and a mirror surface symmetrical about the light axis. Luminous flux emitted from the light source is reflected from the reflector. In the case of the parabolic mirror, the front mirror has the same size as an entrance of an output light utilizing optical system, and the luminous flux exits toward the optical system as collimated light. In the case of the ellipsoidal mirror, the front mirror is arranged between two focal points of the ellipsoidal mirror, and the luminous flux is directed toward the second focal point. However, at least one part of the luminous flux is reflected from the front mirror and returned toward the first focal point.
