    摘要： Improved architecture for a projector (28) comprising a light source (24) in the form a lamp with a curved reflector with a distinctive focal distance for converging the light beam of the lamp; a so called cold mirror (8); an integration rod (11); a relay optics system (15) consisting of a plurality of lenses (16-20) followed by a light valve (21), characterised in that the architecture allows for the use of light sources (24) with different focal distances.

    摘要： The present invention provides a small projection type display apparatus capable of suppressing an optical path of incident light and an optical path of output light in a reflection type light valve from being overlapped with each other and obtaining a projected image of high quality; a rear projector and a multi-vision system using the same. The projection type display apparatus is composed of an illumination optical system 2 for collecting light radiated from a light source 1 to form illumination light, a reflection type light valve 6 for reflecting the illumination light to output modulated light forming an optical image, a projection lens system 7 for projecting an optical image formed by the reflection type light valve, and a lens element 5 with a positive power. The lens element 5 is composed of one plano-convex lens, and is placed between the reflection type light valve and the projection lens system with a convex surface directed to the projection lens system, in such a manner that the illumination light passes through the lens element to illuminate the reflection type light valve, and the modulated light output from the reflection type light valve passes through the lens element to be incident upon the projection lens system.

    摘要： An illumination source or condenser (10) used to project the image of a reticle (24) onto a photosensitive substrate (28) used in photolithography having a first reflective fly's eye, faceted mirror, or mirror array (16) with predeterminedly positioned facets or elements (42) and a second reflective fly's eye, faceted mirror, or mirror array having predeterminedly positioned facets or elements (52). A source (12) of extreme ultraviolet electromagnetic radiation is provided to a first fly's eye or mirror array (16) with arcuate shaped facets or elements (42). The arcuate shaped facets or elements (42) are positioned to create an image of the source (12) at a corresponding facet (52) in a second reflective fly's eye or mirror array (18). A desired shape and irradiance together with a desired radiant intensity, pupil fill, or angular distribution is obtained. The illumination system facilitates imaging of feature sizes 0.025 microns.
