Strange-Jones (or Jones-Strange) is a relatively new design, just like Wiedemann/Busack/Riccardi/Honders medials (even newer). I think it was made possible with advancements of computer optimization routines and is deceptively simple. It is loosely related to Schmidt. Two large lenses, one mirror and one small lens. It can also be made into a Cassegrainian form (in which case of course can't be
as fast, but still
very fast, as fast as f/3.5 ). In Schmidt-like configuration it is easy to make them as large as 500mm at insane f/1.5, still diffraction limited over a huge area (much larger would not be practical as lenses are thick).
It
can cover larger area much larger than 35mm (I've designed 300mm f/3 covering >100mm circle with 3 micron spots). If you factor in the resolution, and the fact that these systems work over enormous spectrum (400nm to over 1000nm), I think you will find out that they are actually capable of resolving more pixels per field than those 1M$ Perkin Elmers. That is, if we could find a CCD/CMOS chip that is large enough, with small enough pixels (and doesn't cost as much as Sydney Opera House).
I'm not aware of any web sites covering them, you have to keep up with Joneses
(Ed Jones and Mike Jones that is
).
I have designed many of those in Zemax, but not aware of anyone having them made (yet).
