Grating ruler manufactured by adopting laser engraving technology

The utility model relates to a grating ruler manufactured by adopting a laser engraving technology. The grating ruler comprises a substrate, the substrate is covered with a film layer, a plurality of scale marks are arranged on the substrate covered with the film layer at certain intervals, and the scale marks are carved on the substrate through laser. The grating ruler manufactured through the laser engraving technology is simple in manufacturing step, only the film layer covering step and the laser engraving step are needed, and the machining efficiency is high; in addition, the grating ruler can adopt substrates made of different materials such as metal, ceramic, glass and the like, and is wide in application range. 本实用新型涉及一种采用激光雕刻技术制造的光栅尺；所述光栅尺包括基板，所述基板上覆盖有膜层，覆盖有膜层的所述基板上按一定间距排列有多条刻度线，所述刻度线通过激光在所述基板上雕刻而成。采用激光雕刻技术制造的光栅尺，制造步骤简单，只需覆盖膜层步骤和激光雕刻步骤即可，加工效率高；并且该光栅尺可采用金属、陶瓷、玻璃等不同材质的基板，适用范围广。
