Fresnel lens design

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.

Mike have a look at this site:
http://fresnel-lenses.globalspec.com/Industrial-Directory/fresnel_lens_design

Look at the first of the web results.

Also, have a look here:

Very intersesting.

you'll get better answers at sci.optics

 

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.

go to the macro library link, it's a macro called eqspline

And yet another very interesting article.

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...

Ought to be a series of spherical or parabolic sections.

Including all the steps?
