    Allow me to repost  here for depth/frequency setting .2ZFJ.Z"  
    The main fresnel lens types are: $ 1m}lXk  
    hR.vJ2oa  
        * Constant groove depth. uK ,W  
        * Contant groove pitch types. LPca+o|f  
    mwI7[I2q  
    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. Y; to9Kv$

    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. *{\))Zmhd

    For conic: check conic section using Wikipedia and you should see what conic constant means. UG}2q:ST
