I guess the main confusion of defining this lens is probably the setting of depth/frequency. 7VJf~\%1j

The main fresnel lens types are: b{W ,wn

    * Constant groove depth. &jDRRT3  
    * Contant groove pitch types. 6uFGq)4p@

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. }Z
