    Allow me to repost  here for depth/frequency setting I4|LD/b  
    The main fresnel lens types are: 85x34nT  
    yk0tA  
        * Constant groove depth. ;J@U){R  
        * Contant groove pitch types. A"B#t"  
    ;A G&QdTMh  
    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. 2tb+3K1

    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. {#.<hPXn

    For conic: check conic section using Wikipedia and you should see what conic constant means. 5tI#UBha
