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 IooNb:(  
The main fresnel lens types are: Xe+,wW3YF  
4m-I5!=O  
    * Constant groove depth. /1`cRyS  
    * Contant groove pitch types. t]-uw-E  
xE-7P|2  
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. $Q+s/4\  
6/ `.(fL1  
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. PNeh#PI6)  
\x>65;  
For conic: check conic section using Wikipedia and you should see what conic constant means. _e!F~V.
