| Summary: | The utility model relates to a high-precision grating sheet; a plurality of cylindrical lenses are tightly distributed on the front surface of the grating sheet; the back surface of the grating sheet is a plane; and the grating sheet is characterized in that the amount of grating lines of the grating sheet is 160.5-161.5. Perferably, the thickness of the grating sheet is 0.18-0.6mm. The grating sheet can be manufactured through once molding, has high transparency, good moldability, high definition and strong focusability, does not deform easily and is easy in post processing. The cylindrical lens grating sheet adopts high-density grating spacing design and has extremely high fineness, and generally, the viewing distance is 0.15-1m; therefore, the grating sheet is very suitable for value-added decoration of various commodity packages and also can be used for ornamental fittings of various articles for daily use, such as pendants, bookmarks and magazines. The high-precision grating sheet is matched with corresp |
