    • An illumination system comprises a light source unit, a condenser lens, and a lens for constructing a telecentric optical system, and projects measuring light onto a specimen to be measured, from an angle tilted by a prescribed angle relative to the normal to the specimen. A light receiving system is an optical system comprising the lens, a light receiving lens, and a light receiving sensor and, of the reflected light produced by reflection of the measuring light, the light receiving system receives reflected light rays reflected in a direction whose angle to the normal to the measuring surface is 0°. In this way, the telecentric optical system is constructed by placing the lens in the light paths of the illumination system and the light receiving system; with this configuration, the projection angle of the measuring light to the curved specimen and the receiving angle of the reflected light from the curved specimen, respectively, can be made the same within the curved surface of the specimen.
    • 照明系统包括光源单元,聚光透镜和用于构造远心光学系统的透镜,并且从相对于样本的法线倾斜规定角度的角度将测量光投射到待测量的样本上。 光接收系统是包括透镜,光接收透镜和光接收传感器的光学系统,并且通过测量光的反射产生的反射光,光接收系统接收在角度方向上反射的反射光线 到测量表面的法线为0°。 以这种方式,通过将透镜放置在照明系统和光接收系统的光路中来构造远心光学系统; 通过该结构,能够使测定光与弯曲试样的投影角度和来自弯曲试样的反射光的接收角度分别在试样的曲面内相同。
