zemax设计菲涅耳透镜时，  fresnel1参数中+Depth/-Freq、Radius、conic分别指什么？

hopebox真的是无处不在

Thanks very much

hopebox确实无处不在啊，能不能加你qq？

Thanks very much!

Allow me to repost  here for depth/frequency setting ]Y| 9?9d  
The main fresnel lens types are: >"@?ir  
7]%Ypv$  
    * Constant groove depth. Vm|Y$C  
    * Contant groove pitch types. d|*"IFe  
Z-B%'/.  
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. j}AFE

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. $ A9%UhV

For conic: check conic section using Wikipedia and you should see what conic constant means. dna6QV>A
