Three sets of lens array (LA) uniform illumination system were designed, which were used in double-frequency laser direct drive experiments on “Shenguang-Ⅱ” laser facility. Experimental investigations on shock planarity were carried out. The results show that the shock planarity has strong relationship with the LA's parameters, plane target's thickness and target's position. The shock planarity driven by the LA with 121 elements is the best, and which indirectly indicates that the illumination of the 121-element LA is the most uniform, too. Moreover, with the target thickness increasing, the shock planarity becomes worse, and the planar area becomes smaller. Also, the shock planarity showes some periodical change with the target's position, and the shock planarity at focal plane is the
