Well, and old collectors rule is "everything comes to him who can wait" - that it would be 16 years when I first learned about that lens and personally had contact with its inventor, I had not really expected.
A few days ago I closed a deal for three prototypes of those lenses, from the heritage of the inventor in California, Richard Nye, who passed a while ago. His company, Nye Optical does not exist anymore. And a big THANKS goes to a friend that helped me getting those lenses!
So, the scientific lenses he invented and custom made were for deep UV recording (capable to work beyond beyond 200nm, especially made to record the 121nm Lyman alpha lines - only in vacuum or nitrogen atmosphere of course), but having no chromatic aberration also in VIS and IR. It is a pure lensless catoptric (reflex) Cassegrain design, which came in f2.8/200mm and f1.1/90mm versions for FF cameras (43mm resp. 25mm image circle, the latter for image intensifiers), focusing from 10 inches to infinity and some adjustable 50mm back focal length.
Well, the three lenses (two 2.8/200mm and one 1.1/90mm) have arrived and of course I was curious to see what they would do.
So here a first visible light shot using that Lyman Alpha f1.1/90mm lens - in one word "craaayyyzzzeehhh"...
DOF at one (1) meter (3ft) is as thin as a razorblade, doughnut shaped bokeh etc. makes it fun.
Inside is an about 25mm (1") thick quartz (ZERODUR most likely) mirror block, front aluminized plus a secondary mirror (most likely made of the same material) held by an adjustable spider in front of that one. Quite built like a small 90mm Cassegrain telescope. _________________ Klaus - Admin

Thats a real photographica porn. I would give and do nearly everything for them
That really looks like a lot of fun! Do they have any kind of aperture?
How do they perform for photographic uses near infinty or with a stacked focus?
Most interensing for me: What was their original use? Are they made some kind of an special atomic emission detector (for example ICP-OES) or a special UV/VIS device,...etc.? Do you know that? _________________ I'm not a collector, I'm a tester

It is clear that you are happy with that lenses. Congratulations!
But what to do with them for what they are made????
I am only puzzled.
Does they give an important extension to your possiblities to do UV-photography? |

very nice. I love that bokeh. unique indeed.
so now you need to get an UV converted body, or do you have one already?
IR, UV (and different wave lengths) are interesting.
I m not sure how many of us are playing with invisible lights.

I knew that.
I'm also amazed that things such as these, obviously made for scientific research, can be used to make such interesting images. To someone like me who has no understanding of the technicalities it's fascinating.
Thank you for showing us, let's see some more. _________________ LENSES & CAMERAS FOR SALE.....

Well, my intention with them is mainly for my UV work as some here that know me could have guessed.
But it makes for interesting lenses anyway too, even if there is no aperture in them, nor any glass lens...
Here is more : http://www.flickr.com/photos/kds315/sets/72157629157849861/
On my BLOG www.uvir.eu , there is more about that lens, as well as about my UV work

I was intrigued, so I looked at your blog and Googled "Cassegrain astronomical telescope" - http://en.wikipedia.org/wiki/Cassegrain_reflector
It's become a bit clearer now, and very interesting. And from a non scientific view, the images are stunning in their own right. _________________ LENSES & CAMERAS FOR SALE.....

I read that it's made for deep UV recording and lyman alpha lines but I don't where to photograph these on earth, except some very special purposes like making atomic emission visible etc.. But why using such a long focal length for that purpose? Or is their intent not further specified? _________________ I'm not a collector, I'm a tester

Ah now I understand their weird attributes Thank you!
I will have a look for similar lenses in automatic sequenzers etc. when the next DNA- or medical reserch laboratory is quitting here

I love invisible "light" too - but more the near infrared part as hobby.
I worked for a company as a service technician for infrared (thermal) and highspeed video. Now the company I work for today, bought a manufacturer of different infrared (thermal), highspeed, x-ray and UV cameras.
So I plan to go a bit further into such non-visible radiation. _________________ Camera modification, repair and DIY - some links to look through: http://www.4photos.de/camera-diy/index-en.html
