I guess the main confusion of defining this lens is probably the setting of depth/frequency. q`2dL)E
p )JR5z The main fresnel lens types are: M]{~T7n- T>nH= * Constant groove depth. Wgte.K> / * Contant groove pitch types. gw,K*ph}q X+A@//,7 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. Y3[KS;_fr9 >e6 OlIW Hope this helps!!

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