The lens system is configured as a whole system so that optical aberrations at the intermediate real image, including field curvature, focus, astigmatism, distortion and color separation, are allowed to be of substantially greater magnitude than the corresponding optical aberrations of the final image.

摘要： A projection zoom lens system of the present invention having telecentric incident side is suitable for a projector apparatus using LCD or DMD with prism. The projection zoom lens system of this invention comprises five lens groups having, from the screen side, negative, positive, positive, negative and positive power. In addition to this arrangement, since the lens located closest to the screen is a screen side convex negative meniscus lens, wide-angled and bright zoom lens system can be realized. Further, by designing the distribution of power of the first lens group located closest to the screen, the projection zoom lens provides further improved aberration correction. As the condition for realizing the aforementioned projection zoom lens system, it is preferable that a focal length f1 of the first lens group and a focal length at a wide-angle end fw satisfy the following condition:-1.9

摘要： An image projector (8, 68) includes a light source (14) that illuminates a three-path reflective LCD assembly (25, 74) that produces images for projection by a projection lens (27). The light source produces S-polarized light rays that are received by a spectrally selective wave plate (36) that changes a first wavelength range of light to P-polarized light rays (34) and transmits without polarization change second and third wavelength ranges of light. A plate-type transflective polarizing beam splitter (40) transmits the P-polarized first wavelength range light rays and reflects S-polarized second and third wavelength range light rays (34). The P-polarized first wavelength range light rays transmit through a field lens (421) and impinge on a first reflective LCD light valve (261). The S-polarized second and third wavelength range light rays strike a pleochroic filter (48), which divides them into second and third wavelength range light rays (44, 46) that propagate through field lenses (422, 423) and impinge on respective second and third LCD light valves (262, 263). The light rays impinging on dark state pixels on the first LCD light valve are reflected without polarization direction change and return toward the light source along their original paths. However, the light rays impinging on illuminated state pixels on the first LCD light valve are reflected with a 90° change in polarization direction and are reflected toward the projection lens by the transflective polarizing beam splitter. The light rays impinging on illuminated state pixels on the second and third LCD light valves are reflected with a 90° change in polarization direction, are recombined by the pleochroic filter, and transmit through the transflective polarizing beam splitter toward the projection lens.
