How do I make a magnifying glass plane?

Question

I'm trying to make a glass plane that zooms in whatever you see behind it, I tried this material from another question but it didn't work

I think what this is supposed to do is to scale all the light that comes through the Z Normals?

For that to work (the IOR 0.0 trick) you need to have the surface normal pointing the correct way - the opposite way to that you would expect. The IOR of zero will effectively direct the incoming rays directly along the Normal - so it can be used to bend incoming (parallel) rays as if the surface acts lens.

Could you elaborate on what raytraced transparency is? – Linguini Oct 14 '18 at 20:05
It's transparency+refractions. See more -> https://docs.blender.org/manual/nb/dev/render/blender_render/materials/properties/transparency.html – Lukasz-40sth Oct 15 '18 at 05:43
