    • A focusing unit can be inserted into and removed from an illumination light path by rotating around a supporting portion. An index light source, a green LED, is attached to the bottom of a base. A transparent acrylic-resin disk is fixed to the base. A deflection prism is attached to the bottom of the disk. A beam from the light source enters the deflection prism. A focus index forming portion is provided on the top of the disk. In the center of a light-shielding portion is formed a slit-like opening, under which split prisms are provided. Deflected by the prisms, the beam from the light source is split into two, right-half and left-half, directional beams, and combined with an illumination optical system, in the form of two slit images, at the opening.
    • 可以通过围绕支撑部分旋转而将聚焦单元插入照明光路中并从照明光路中移除。 索引光源(绿色LED)连接到底座的底部。 透明的丙烯酸树脂盘固定在基座上。 偏转棱镜连接到盘的底部。 来自光源的光束进入偏转棱镜。 焦点指标形成部分设置在盘的顶部。 在遮光部分的中心形成狭缝状的开口,在该开口处设有分割的棱镜。 由棱镜偏转,来自光源的光束被分成两个,右半部分和左半部分的定向光束,并且在开口处与两个狭缝图像的形式的照明光学系统组合。
