    Optics and mathematics: an old problem solved

    Very interesting read (but you will need to hit the translate button if you don't read Spanish):

    I read the article, but I have to admit I did not bother to confirm the math

    I don't think they posted the solution, only the equations that need to be satisfied. It's extremely cool (and rare) to find a closed form solution to a non-linear problem. But grinding an aspherical surface is hard whether you know a formula or you just have a numerical table generated by computer (or some spline or other approximation generated by guys with slide rules). Spherical elements are "easy" to make.

    This also leaves a bunch of other aberrations that need fixing.

    Still, big win!
