Legend of the Ultra Micro Nikkor

Dr. Koana requested the lens which has over 1,000 lines/mm resolution as for the super-micro photographs to Nippon Kougaku.
So Nippon Kougaku tries to make the super high resolution lens, which is based on the 40X object lens (may be the APO PLAN base) of a microscope.
The Nippon Kougaku developed this lens as standard magnification is 1/25X under e-line monochromatic lighting (wavelength 546.1 nm).
This lens was the first lens which has multi coating.

August, 1964.
And finally, a legendary super high-end lens, Ultra-Micro-Nikkor 29.5mm F1.2 was developed successfully.
The MONSTER LENS which has 1,260 lines/mm resolution was born.
This lens has nine elements in six groups. Distortion is -1.3%. It weighs only 800g.
Of course this lens was designed by Nippon Kogaku's genius engineer Mr. Zenji Wakimoto.

Dr. Koana tried to make the reduction copy of all the English novel pages into a small postage stamp size using Ultra Micro Nikkor 29.5mm F1.2 lens.
It has 330 pages in the text. However all pages have been reduced to a very small 12.5mm square photograph.
Furthermore, he enlarged from this small size pictures to the original size by using a same lens.
Dr. Koana enjoyed this lens well.

The English novel book he try to make it small was "Lady Chatterley's Lover".
He has the humor sense, because if he choose Shakespeare, the story is not cool.
He made this super micro photograph and read it under a microscope.
This is a great hobby. Will you think so?
