    • A projector includes an illumination device, a color separation system, a light combining system, a projection system, and an optical adjustment portion. The color separation system separates the light emitted from the illumination device into blue light, red light, and green light. The light combining system can have a first dichroic filter reflecting one of blue light or red light, and a second dichroic filter reflecting green light which are placed in a crossed state and can combine image lights of respective colors exiting from the first through third light modulation devices. The projection system can project a combined light exiting from the light combining system while correcting chromatic aberrations of magnification of blue light and red light with respect to green light. The optical adjustment portion can adjust a size of an image light corresponding to the green light of the combined light exiting from the light combining system.
    • 投影仪包括照明装置,分色系统,光合成系统,投影系统和光学调整部分。 分色系统将从照明装置发出的光分离成蓝光,红光和绿光。 光组合系统可以具有反射蓝光或红光中的一个的第一二向色滤光器和反射绿光的第二二向色滤光片,其处于交叉状态,并且可以组合从第一至第三光调制出射的各颜色的图像光 设备。 投影系统可以投射从光合成系统出射的组合光,同时校正蓝光和红光相对于绿光的放大倍数。 光学调整部可以调整与从光合成系统出射的组合光的绿光对应的图像光的大小。

    • To provide a projector that hardly causes deterioration of an image resulted from stray light. A neutral density filter, of which posture can be fine-adjusted by a posture regulating mechanism, is placed in a space between a second dichroic mirror and a liquid crystal light valve. Thus, it is possible to remove stray light, corresponding to condensed light resulted from multi-pass through a field lens or the like, to the outside of a light path by merely tilting the neutral density filter adequately. It is thus possible to project an image having homogeneous brightness (illuminance at the white level) across the entire screen, which in turn makes it possible to project an image having no irregularities in color across the entire screen.
    • 提供几乎不引起由杂散光引起的图像劣化的投影仪。 可以通过姿势调节机构将姿势微调的中性密度滤光器放置在第二分色镜与液晶光阀之间的空间中。 因此,通过适当地倾斜中性浓度滤光器,可以将对应于多次通过场透镜等的聚光的杂散光移除到光路的外部。 因此,可以在整个屏幕上投射具有均匀亮度(在白色水平的照度)的图像,这进而使得可以在整个屏幕上投射没有颜色不均匀的图像。
