I guess the main confusion of defining this lens is probably the setting of depth/frequency. +]{G@pn LCV(,lu The main fresnel lens types are: )J(6xy &m;*<}X * Constant groove depth. 42ge3> * Contant groove pitch types. -jmY)(\ )NT*bLRPQ So if your depth is fixed you will define +ve value in the cell and to specify the "height" or "depth" of each groove feature. If the frequency of the groove is fixed then you use -ve value. Say putting down - 5 this implies that there are 5 grooves with a unit length. (+hK%}K> P@~yx#G Hope this helps!!

我们是做翻版模具的 用传统机械方法制作模具费时费力而且损耗大,我们可以用金属的电解沉积原理来精确复制某些复杂或特殊形状工件,完全可以解决这个问题。如果母盘制作精确复制可以做到一模一样。 M

Q6!zZ))~ are you using mixed mode, defining the Fresnel lens under non-sequential mode? If so, please check the port setting.
