the Argolight slide has a sphere made of 3 rings: one in xy, one in xz
and one in yz. Also, there are several z-stair patterns on it, with
different z-step sizes. It sounds like you would prefer a cube with a
3D-dot pattern (which might be a good idea for future versions) but
maybe one of those patterns would do. argolight.com
It is not cheap, but it gives you a lot of options for quality control.
If you should have money to burn, you might get a custom pattern. No
commercial interest on my side.
Out of curiosity. should you not be able to see 3D distortion if you
focus through a 2D pattern? Not that I would know much about grin
lenses. At the end of the day, every available detector just takes a 2D
image at max, and assembles 3D in the computer.
