求进牌大画幅镜头。300MM F5.6.

。。。。。

全新的早期长春产大画幅镜头。

Something very different, a mirror lens with built in quite interesting aperture
which is fan shaped and regulated by adjusting the angle of the blades!

And it is a very fast one, too, a f1.4 150mm lens (!!) made for scientific research
of which very few have ever been made and sold.

镜头收藏家Klaus的稀有藏品。可以调节进光量的反射镜头。150mm F1.4!

神秘的优质国产镜头。上照四厂产的58MM F4镜头。

再来一台。

老相机上不同寻常的镜头。

这几样东西里最稀有的是那个镜头盖，

另一只稀有的缩微镜头。

最近出现的稀有工业用镜头。缩微镜头，做半导体电路的。不是我的。

神秘的镜头，比XXXXXXX还神秘的。无名，无产地，无。。。。。。任何信息，

一些稀罕的镜头。平常见不到的，比官员的二NAI还难见到。

          I relisted, because the dude who bought it did not realize that he has to pay it.
The tripod, head and focusing unit shown on the picture are not included in this auction!
        
                                                   Huge ! ! !

Huge mirror lens 2540mm focal length, aperture F/8 ! ! !
These lenses were used by the NASA for tracking the Saturn V or similar.
I was told by the grandson of its producer John H. Ransom, that the tragedy of  
the Space Shuttle Challenger was tracked and filmed with Jonel lenses
( the most of them are still in use ).
They used high speed 70mm movie cameras like the Photosonics 70mm 10R with
up to 125 fps on 6x6 frames ( this camera is also for sale, seperate )
It is a Schmidt-Cassegrain design with a two element field corrector to produce a 57x57mm image format ( 80mm image diameter or more ).
This lens is unique. Optics mint, barrel mint- ( some loss of paint ).
The barrel is incorporating a system to avoid humidity inside, it is very rigid, and the design is very sophisticated, compared to modern Astro cameras.
I added a test shot : a blow up of a raw file ( Canon EOS 600d ), taken with the big
brother of the Jonel 100, the Jonel 200 ( 5080mm F/16 ) at 600 feet distance.
The diameter of the small star sector target was 40mm. Resolution is a little more than
100 lines per mm ( 50 line pairs per mm ) with the Jonel 200, and will be a bit more
with the Jonel 100.
Original costs (for NASA) : about one family home.
180 pounds in original case. Ask me for tripods, heads and for focusing units.
You may compare it with the actual lenses from Brashear ( 50"/ 100"/ 150" ). And by
the way, ask them for their pricing  . . . . .  :-)

One word to those " buy a 12" Meade AND a home " astro-dudes :
Astrograph Veloce RH 300 f/3 with just 60mm image circle . . . but again, the design
of the Jonel is much more sophisticated.
Please also check the Carl Zeiss Mirotar 5,6/1000mm, designed for 56x56mm,
( the sharpest non military Telelens for 6x6 ).
I wish I had a 8/2540mm Mirotar, but the cost would be more than 10 family homes . . .

The picture shows me with the Jonel 200 ( sold ) and a "lightweight" tripod/head
combination ( payload up to 380 pounds ) and a focusing unit, carrying my Pentax 6x7.

貌似也是全金属，全手动的精密东东啊。哪怕是玩也要有点相像力啊。开辆法拉利跑车开的比走路还慢不能不说也是一种情趣。

来自这辆弹车。主镜头下面那只。他真用它拍照。

一位美国网友收藏的※※跟踪仪上的镜头。

相机下的是什么？ 是那个2000MM F7※※跟踪仪镜头的镜头盖。 也是全金属的。呵呵。 本帖最后由 Kievuser 于 2016-5-15 21:27 编辑

新浪网关于稀有镜头拍卖的消息。45万美元可以在2-3线城市买一套房子了。

http://collection.sina.com.cn/hwdt/2016-04-25/doc-ifxrpvea1173846.shtml

Very rare f1.8 (!!!) 45mm $$.$$$ quartz fluorite lens, suitable for UV (ultraviolet) light, fastest I ever saw in my life.

著名的KLAUS 博士是个镜头专家，收藏了很多稀有的镜头，这是他的藏品之一。

蔡司的物镜每只都有这种文件吗？还是只有高档的，1万美元以上的才有？

一些国产的M19接口平场无穷远物镜。 本帖最后由 Kievuser 于 2016-5-6 06:47 编辑

高档特种物镜挺有趣。目前好像只有德国，日本能生产？

一些带厂标的国产显微镜物镜。

好奇最顶级的显微镜物镜的价格是多少，如果不算顶级光刻镜头的话？

网上资料：

Zeiss C-Apochromat 40x/1.2W ∞/0.14-0.19 (44 17 57 – 9970). RMS thread and 45mm parfocal. One of Zeiss's elite objectives with a list price for the latest M27 version just under ￡14000 in the UK.

Maximal light gathering in confocal, 2-photon and general fluorescence work.

Image quality is second to none; flat (fully plano-corrected), contrasty, strain-free for pol and DIC, and aberration-free, it is a great joy to use.

This objective will give the highest possible resolution of aqueous specimens and can focus as much as 250 microns deep into the specimen with great optical sectioning. The ultimate viewing of "pond life"!

Little used and in as-new condition, and very rare indeed on eBay. I've set the BIN price at under 20% of new cost so a real bargain if you need one.

最近买了一台早期※※格勒旁轴，就是为了它的取景器。总产量7万台的※※格勒旁轴里取景器好的估计不到1/10？

很好的资料。

新华社柏林１１月２３日电：２００６年度德国“未来奖”于２３日揭晓，凭借发明突破２００纳米“阿贝极限”的光学显微镜，德国马克斯－普朗克学会生物物理化学研究所所长施特芬·黑尔获得了这一荣誉。

        一年一度的“未来奖”是德国最重要的科学奖。黑尔在接过德国※※克勒颁发的奖杯时表示，将把所获得的２５万欧元奖金作为一个科技公司的启动资金，为将来研究更好的显微镜奠定基础。

        １８世纪７０年代，德国物理学家恩斯特·阿贝发现，可见光由于其波动特性会发生衍射，因而光束不能无限聚焦。根据这个阿贝定律，可见光能聚焦的最小直径是光波波长的三分之一，也就是２００纳米。一个多世纪以来，２００纳米的“阿贝极限”一直被认为是光学显微镜理论上的分辨率极限，小于这个尺寸的物体必须借助电子显微镜或隧道扫描显微镜才能观察。但黑尔等科学家却巧妙地借助脉冲激光的作用，突破了“阿贝极限”。他们发明的新型的光学显微镜能够观察２０纳米左右的微小生物。

        据悉，这种新型光学显微镜将于明年投放市场，预计价格在８０万欧元左右。

10年前的消息。不知道这种新显微镜长什么样？
