I'd like to model a Fresnel lens, but having a hard time finding the spec's for the geometry. Can anyone help? Thanks.

Do a Google Images search on Fresnel lens and you will find several sites that describe the lens theory and shape. I didn't go through all of them, but there might be enough info for you to get close.

Once you get an equation for the cross section of the lens, I have a macro on my website that will create a spline from your equation.

Hi, Thanks everyone for your input. I found the same references you did, but I guess I'm looking for the "easy" way out; I'd like to see something that says "DO THIS"... haven't found it yet...
