    • A projection optical system has first to fourth lens groups (51) to (54) provided in this order from a SLM, a mirror (32) having an opening is provided between the first lens group (51) and the second lens group (52), and an aperture plate (132) is provided between the third lens group (53) and the fourth lens group (54). Zeroth order light which is signal light from the SLM passes through each opening of the mirror (32) and the aperture plate (132) to be guided to a recording medium, and a part of first order diffracted light is reflected by the mirror (32) to be guided outside and received by an external light-block water-cooling jacket. The rest of the first order diffracted light is blocked by the aperture plate (132), and heat generated by light blocking is removed by a cooling mechanism connected to the aperture plate (132).
    • 投影光学系统具有从SLM依次设置的第一至第四透镜组(51)至(54),具有开口的反射镜(32)设置在第一透镜组(51)和第二透镜组(52)之间 ),并且在第三透镜组(53)和第四透镜组(54)之间设置孔板(132)。 来自SLM的信号光的零级光通过反射镜(32)和孔板(132)的每个开口以被引导到记录介质,并且一级衍射光的一部分被反射镜(32)反射 )被引导到外部并由外部光块水冷套接收。 第一级衍射光的其余部分被孔板(132)阻挡,并且通过连接到孔板(132)的冷却机构去除由光阻挡产生的热量。

    • A laser beam emitted from a laser light source passes through an illumination lens and is thereafter incident upon a total internal reflection prism. The total internal reflection prism bends the laser beam, which is applied to a Grating Light Valve™. The laser beam divided into a number of beams and modulated by the light valve is incident upon a focusing lens. The normal to the light valve forms an angle &thgr;xz with the optical axis of an illumination optical system including the total internal reflection prism and an illumination lens. The normal to the light valve also forms the angle &thgr;xz with the optical axis of a focusing optical system.
    • 从激光光源发射的激光束通过照明透镜,然后入射到全内反射棱镜上。 全内反射棱镜使施加到光栅灯(TM)的激光束弯曲。 被分为多个光束并由光阀调制的激光束入射到聚焦透镜上。 光阀的法线与包括全内反射棱镜和照明透镜的照明光学系统的光轴形成一角度。 光阀的法线也与聚焦光学系统的光轴形成角度。
