Was waiting and searching over 10 years for such a lens until I finally found it...
It was made for the Soviet MARS 2-5 missions to planet Mars using a very elaborate camera
with a 4/350mm catadioptric quartz fluorite lens [lens drawing made exclusively for me by my dear friend Marco Cavina]:
which delivered very sharp images of the Mars surface:
And here is the lens in unused condition, a spare one of the very few ever made, that did not make it to Mars:
It was designed and made of only Quartz and Fluorite to be able to work in UV and visible light, 300-700nm without focus shift.
So it actually is an APO 350mm catadioptric lens. Its whole useful wavelength range is 230-700nm.
Data of this lens, as well as its normal quartz fluorite sister lenses for the Mars mission are here on my site:

http://photographyoftheinvisibleworld.blogspot.de/2018/02/zufar-4350mm-quartz-fluorite.htmlAbout mounting this lens: I have measured the back focal length (BFL) to be at infinity about 70-75mm, so there is plenty of room to even adapt it
to Nikon with its long register length of 46.5mm, but I will use it on my mft multispectral cameras most likely, which allow me to have approx. 50-55mm
for a focus mount and also a rear slide in filter holder, most likely the DEO-TECH OWL adapter which I have already here.
