Micro dimple texture should be evaluated from the viewpoints of the following : a shape, a surface quality, a configuration, a performance as an optical surface, and so forth. In this paper, the shape and the surface quality are measured by the techniques of the interferometory and the geometrical optics, respectively. The interference fringes indicating the error from the designed shape were obtained by Twyman-Green interferometer. And the patterns of the tool mark on the surfaces of the dimple were visualized by the ray tracing method. The pattern agreed well with the pattern obtained by theory.
