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
(https://nikongear.net/revival/proxy.php?request=http%3A%2F%2Fwww.macrolenses.de%2Fbilder%2FV_CameraM5d_b_wp_b.jpg&hash=56c31d2ac9563d4697ec2db9ef4e475af9f856a0)
with a 4/350mm catadioptric quartz fluorite lens [lens drawing made exclusively for me by my dear friend Marco Cavina]:
(https://nikongear.net/revival/proxy.php?request=http%3A%2F%2Fwww.macrolenses.de%2Fbilder%2FLomo_Zufar_1_2_wp_b.jpg&hash=70f2fb300132811d02044270ed4ca72b21b1c325)
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:
(https://nikongear.net/revival/proxy.php?request=http%3A%2F%2Fforum.mflenses.com%2Fuserpix%2F20182%2F455_ZUFAR_350mm_IMG_9958a_c_1.jpg&hash=e606bea706077120c10448188b7b18a49163e6cb) (http://forum.mflenses.com/userpix/20182/big_455_ZUFAR_350mm_IMG_9958a_c_1.jpg)
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://www.macrolenses.de/ml_detail_sl.php?ObjektiveNr=323 (http://www.macrolenses.de/ml_detail_sl.php?ObjektiveNr=323)
More may be read about it here on my Blog:

About 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.

Here a few freelensed test shots on a gloomy day...
About 100m away:

Amazing find! I'm looking forward to seeing the images in UV!

Congratulations, truly a special lens! Enjoy ;)

Well, here the 1st reflected UV image I took with it...handheld freelensing, high ISO:

whitebalanced it looks like this:

Looks like impeccable...

Pretty happy with it so far, considering that I don't even have a mount for it yet...

Looks beautiful. Congratulations with your very special find.

Awesome Klaus!

Now, that's what I call patience ... :o 8)
Good for you ... cheers (https://nikongear.net/revival/proxy.php?request=http%3A%2F%2Fnikongear.online%2Fimages%2Fsmilies%2Fbier.gif&hash=93ec1e8227aade962779f98b3025cbe0ee902474)

Thanks guys, appreciate it!

Trying to see how well it does closeups...
Here a Balinese Sandlewood carving shot against the light (no hood used):

Both about 3 meters away

And here a quite better focused image of my standard target, that golden ball at sunny weather:

"Long and sharp and red" (Savage Rose: 'Sunday morning')
I always wanted to go to Mars. Finding such lenses there makes the wish more urgent :D

Well, Mr Elon Musk is working on that intensively, maybe get in contact with him ;-)

Sharp and red like that roadster now coasting to Ceres!
If that DEO-TECH OWL doesn't suit you might consider the Starizona Filter Slider.

I have one and it is quite robustly built.
If the diameter is similar you could drill and tap holes for your lens mounting flange.

Thanks John, I have already several alternative filter silders here!

Aww yeah, I can feel your joy :)
Looks absolutely amazing, the results are looking great too. Just wondering, how much did you pay for it? I have a hard time finding weird exotic stuff online. ::)

Well, I'm quite excited to report that I just found and bought the grandfather of this ZUFAR-2 space lens from the Russian planet Mars exploration, thanks to my russian friend(s). It is a prototype lens with a very different internal name Ob-512, but company data (LOMO) confirmed my suspicion, it is indeed one or even "the" factory prototype of it.
(https://nikongear.net/revival/proxy.php?request=http%3A%2F%2Fforum.mflenses.com%2Fuserpix%2F201811%2F455_Zufar2CA_Ob512_c_2.jpg&hash=ab8a2ec3d1e8d0269858b535052c29f3966ce53c) (http://forum.mflenses.com/userpix/201811/big_455_Zufar2CA_Ob512_c_2.jpg)
Zufar-2 CA on bottom, Ob-512 protoytpe on top
Bit larger, quite heavier the prototype was - they changed the materials for the final product and saved aprox 20% weight (2.2 kilograms down to 1.8 ), very important for a 1976 space lens. The technical data of the final lens got also improved, viewing angle from approx. 3 degrees to 5 degrees, UV-VIS transmission from >50% to >57% (200-700nm). Back focal length remained at 51mm, very useful for a later adaptation...

Apparently a very useful friend .... looking forward to actual images.

Wahnsinn, Klaus. 10 Jahre warten und dann. Gratuliere!!!

Yep, that's what I expect it to be! I will certainly take some images, but in December when it finally will have made it here, there won't be much left to show...
Wahnsinn, Klaus. 10 Jahre warten und dann. Gratuliere!!!
Das war für das ZUFAR-2, dieses hier hat mich gefunden... ;-) Dankeschön!!

Amazing story. Congrats, Klaus!
