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

Allow me to repost  here for depth/frequency setting ;K`qSX;;c(  
The main fresnel lens types are: W4X=.vr  
TTBl5X  
    * Constant groove depth. @m#7E4+  
    * Contant groove pitch types. S_1R]n1/  

^e)KEkh  
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. St'3e<  
mKn:EqA  
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. 8 \%*4L'

For conic: check conic section using Wikipedia and you should see what conic constant means. \V}?
