Could anyone recommend a good vendor for custom pitch-polished, glass
toroidal mirrors? This is for use in the visible, and close to spherical.
Specs are about 1 wave figure and 0.5% radius. We have found lots of peope
who claim they can make it, but say they do not have any ability to test
toroids. Other vendors that make VUV or X-ray substrates are very
expensive. I know of methods to test toroids that we could teach to a
vendor, but I would prefer one that already has this experience.
Thanks,

Try Cody Kreisher at Kreisher Optics. If he can't do it and doesn't
know who can you're probably out of luck. (If the part is large
Tinsley may also help.)
As your part is only slightly toroidal an alternative may be to slump
a spherical mirror. There are few companies who CLAIM to be able to
do this.
(If your application is close to monochromatic a holographic or
digital optical solution may work for you. However, I assume you've
checked alternatives to eliminate such a nasty element.)

Thanks, I will check them out.

I thought the Zeeko machines could only make rotationally symmetric
aspheres. Have they introduced something new?

I recall seeing one of their machines making a convex toroid shape by
doing an xy raster.
I watched it in person, but they may have changed their machine
configurations since then.
I would guess that if zeeko cant the MRF machines should be able to
and Cody has one of those.
Let us know what you find out.
You might also check with bob parks who was involved with the original
Optics Cooke Book on optical fabrication and testing;

Figure out how many diopters power, tangential and sagittal for a
transmission lens would give the proper radius on the second side
given the spherical radius of the first side of an ophthalmic eyeglass
lens. These lenses come with a spherical curve on the front side.
Hint, Getting the optician to understand that you do not want a lens,
but only care about the second surface is the hardest part.
I find most optometrists can't understand what you want either.
You will need to learn the specing procedures for eyeglasses very well
to defeat the system.
You will need the index of refraction of the material, and the
wavelength, and material for which the diopter tools are ground at the
optican's shop.
When it works you get a $25 toroid that is really very nice.
I don't know about 1 wave, but you could buy 100 and select for less
than what you would pay for a toroid made on a custom overarm, or log
machine with bending.
