PROJECTION APPARATUS

摘要

In a projection apparatus, a light beam emitted by a light source is guided to a modulation element for forming an image. The light beam emerged from the modulation element is projected onto a screen by a projection lens. An image of the light source is formed as a first light source image by a first optical system. The light beam from the modulation element illuminated with light emanating from the first light source image is imaged by a second optical system as a second light source image at a potion in the vicinity of an aperture of a stop of the projection lens. A peripheral portion of the first light source image is intercepted by another stop located at a potion conjugate with the stop of the projection lens.
