摘要： In a projection system wherein an optical system comprising a first lens for correcting a spherical aberration dependent on the aperture length, a second lens for enlargement and a third lens for correcting a field curvature, projects an image reproduced on a CRT having a curved phosphor surface, onto a screen, the third lens is spaced from the CRT so that the region of the phosphor surface which again totally reflects a light which has been totally reflected by a screen-side surface of the third lens is limited to the edge portion of an effective region of the phosphor surface.

摘要： An improved lens system for a projection television is described. The lens system is designed to be used with a cathode ray tube having a face glass with an aspheric surface having phosphor elements mounted thereto. The aspheric surface of the face glass has its maximum radius at the optical axis and is of lesser radius outwardly thereof. From the screen, the lens system companies a first aspheric lens of relatively weak power, a second biconvex lens of relatively high positive power, a third aspheric lens of weak positive power and a fourth lens having a concave face on its screen sider and of relatively large negative power.

摘要： An ultra-wide angle liquid crystal projector system comprising a light source, a liquid crystal panel, a curved screen, and a projection lens for projecting in accordance with light emitted by the light source an image formed on the liquid crystal panel onto the curved screen. The projection lens has a curvature of field substantially conforming to the shape of the curved screen and an angle of projection of at least 120 degrees. The projection lens is disposed with respect to the curved screen so that a distance from an exit surface of the projection lens to the curved screen is less than 3 meters.
