Brief information on

Nikon / Nippon Kogaku Japan Ultra-Micro-NIKKOR 1:2.8 f=105mm, 125mm f/2.8, 135mmmm f/4, 150mm f/5.6 lenses

Nippon Kogaku Japan, Ultra-Micro-NIKKOR 1: 2.8 f=105mm
Year introduced: 1962, possibly later with the h-line model, Discontinued: No info

Probably can be regarded as the first of this series. Not much info and neither I have any picture to show this first Ultra-Micro-NIKKOR lens.
   
Nippon Kogaku Japan, Ultra-Micro-NIKKOR 1: 2.8 f=125mm e-line type; Year introduced: 1965, Discontinued: No info

The Ultra-Micro-NIKKOR 1:2.8 f=125 (125mm f/2.8) was. explained in the Nikon Sales Manual on Science and Tecnical Nikkor lenses that it was an improved upgrade to the UMN 105/2.8 (although the focal length had increased from 105-->125mm. The main function of the lens was for making photomarks with "One-Shot method". The picture plance of this lens has been enlarged to match the size of the semiconductor wafer and covers a range of 28mm in diameter. As compare to the UMN 50mm series 14mm image circle, it offered almost 1X larger in coverage.

Even if it was meant for industrial usage, but it was a beautifully crafted lens, solid and well laid out in features for operation.
due to f/2.8, the filter accessory size was quite large@ 72mm, screw-in.

Nippon Kogaku Japan, Ultra-Micro-NIKKOR 1:4 f=135mm e-line type
Year introduced: 1965, Discontinued: No info
This UMN 135/4, share some similarities with the 125mm f/2.8. It was also for making photomasks with One-Shot method or makig intermediate nagative plate for Step & Repeat method. Main difference perhaps was its standard magnification of 1/25X features the large original size of 88~113cm square.

Nippon Kogaku Japan, Ultra-Micro-NIKKOR 1:5.6 f=150mm e-line type
Year introduced: 1960, Discontinued: No info

This Ultra-Micro-NIKKOR was introduced among the earlier stage, approx in year 1960. The ring at the lens barrel was like one of those '60 type of F-mount Nikkor lenses design. The image circle coverage was quite large at 64mm x 95.5mm but as compare to other UMN lenses, the resolution offered was within a so-so range @ 150 lines/mm. The lens was seemingly not like other UMN main purpose in IC/LSI manufacturing; instead, it was more leaning towards to Micro-NIKKOR 7cm f/5 . In fact, I have compiled information of this lens along with the 7cm/5 together at one page summary.

Request: Anyone has better info or pictures of these related optics ? Please mail my buddy: rick-oleson@yahoo.com
