    Allow me to repost  here for depth/frequency setting i]a 5cn  
    The main fresnel lens types are: LJ`*&J   
    7'z{FS S  
        * Constant groove depth. CEq0ZL-W  
        * Contant groove pitch types. <Qu]m.z[  
    F\F_">5  
    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. ='a[(C&Y  
    yt}Ve6  m  
    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. 2Kovvh y#

    For conic: check conic section using Wikipedia and you should see what conic constant means. wZ6LiYiHl
