    Allow me to repost  here for depth/frequency setting +R_U  
    The main fresnel lens types are: $Yka\tS'  
    +D@R'$N  
        * Constant groove depth. G$j8I~E@  
        * Contant groove pitch types. .DQ]q o]OG  
    x#^kv)  
    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. (}:xs,Ax

    For radius, this is the curvature of the base surface. If you define one such lens and chaneg the radius and you shall see what it means. A graphic tells lounder than words. 6PH*]#PfoD

    For conic: check conic section using Wikipedia and you should see what conic constant means. by<2hLB9Q
