    Try googling "Glass sphere optics". I got a few interesting hits.
    I did find this, which may help. The focus of a glass sphere is very close to the surface so multiple spheres would be difficult to use???

    Have you seen them used to record hours of sunshine in seaside towns? They burn a line in a sheet of paper as the Sun goes across the sky.

    See also raindrops and rainbows!
