    • A projector has an illumination optical system, a reflection-type display panel, a projection optical system, and light-introducing device. The display panel is illuminated by the illumination light emitted from the illumination optical system and is divided into a plurality of pixels to reflect the incoming illumination light selectively in accordance with the pattern formed by those pixels and thereby produce projection light. The projection optical system transmits the projection light reflected from the display panel to project the pattern formed by the pixels onto a projection plane on which to form a projected image, and is composed of, from the projected-image side, a front lens unit, an aperture stop, and a rear lens unit. The light-introducing device is disposed between the front and rear lens units and directs the illumination light to the display panel. The projection optical system fulfills the condition 0.2≦&ggr;F≦0.8 where &ggr;F represents the angular magnification of the front lens unit.
    • 投影仪具有照明光学系统,反射型显示面板,投影光学系统和光导入装置。 显示面板由照明光学系统发出的照明光照射,并被分成多个像素,以根据由这些像素形成的图案选择性地反射入射照明光,从而产生投射光。 投影光学系统透射从显示面板反射的投影光,将由像素形成的图案投影到投影面上,形成投影图像,并从投影像侧构成前透镜单元, 孔径光阑和后透镜单元。 光引入装置设置在前透镜单元和后透镜单元之间,并将照明光引导到显示面板。 投影光学系统满足其中γF表示前透镜单元的角放大率的状态。

    • A projecting optical system has a plurality of display panels, a color integrating mirror, a projection optical system, a correcting member, and a lens member. The color integrating mirror, disposed at an angle to any of the display panels, integrates the images displayed on the display panels into a single color-integrated image by reflecting a light component covering a specific wavelength range and transmitting light components covering other wavelength ranges than the specific wavelength range. The projection optical system projects the color-integrated image onto a screen. The correcting member, disposed within the projection optical system, corrects the astigmatic difference caused by the color integrating mirror. The lens member, disposed on the color-integrating-mirror side of the correcting member, corrects the astigmatic difference caused by the color integrating mirror.
    • 投影光学系统具有多个显示面板,彩色积分镜,投影光学系统,校正构件和透镜构件。 与任何显示面板成角度设置的颜色集成反射镜通过反射覆盖特定波长范围的光成分并透过覆盖其他波长范围的光成分将显示面板上显示的图像整合为单一的彩色集成图像, 具体波长范围。 投影光学系统将颜色集成的图像投影到屏幕上。 设置在投影光学系统内的校正构件校正由颜色积分镜引起的散光差异。 设置在校正构件的颜色整合镜侧上的透镜构件校正由颜色一体化镜引起的象差。
