The invention relates to a method for producing a plastic body in crystal optics, in which a plastic material (200) is molded into a plastic body having a plurality of facets in a cavity (110) of a mold (100) which has a first surface texture (120) in the region of the cavity, the first surface texture produces a second surface texture (20) on the surface of the plastic body at least in the region of one facet, which second surface texture serves as a diffraction grating for visible light. The invention also relates to a plastic body in crystal optics and to a vehicle component having such a plastic body. 本发明涉及一种用于制造在晶体光学中的塑料体的方法，其中，将塑料材料(200)在模具(100)的型腔(110)中成型为具有多个棱面的塑料体，所述模具在型腔的区域中具有第一表面纹理(120)，该第一表面纹理在塑料体的表面上至少在一个棱面的区域中产生第二表面纹理(20)，该第二表面纹理用作为可见光的衍射光栅。本发明还涉及一种在晶体光学中的塑料体和一种具有这样的塑料体的车辆构件。
