Fax Nikkor 300mm F7

Fax-NIKKOR lenses have been developed for use on office copying machines.
Copying machines in the 1960's and 1970's were classified: one that makes contact copies and the other that makes photographs of the original by using a lens.
For the latter type high speed lenses for short exposure time were designed by Nippon Kogaku.

The 300mm f/7 Fax-NIKKOR has 6 elements in 4 groups.
The picture angle is 50° with an image area of 630mm and a working distance of 1200mm.
It has no diaphragm, but a slit for slip-in aperture control plates.
With the little button on the side of the lens a simple internal shutter (only "B") is released.
The weight is 1.700g.
Unusual for a Nippon Kogaku lens:
The lens engraving is found on both sides of the lens, including the serial number!

Look!! Shock Absolver Unit Fax Nikkor 300mm has a simple internal shutter unit(only "B"). The knob of side of lens is soft shutter release unit (shock absolver unit). You can press down the shutter release button gently. This unit is usually connected with an electromagnetic shutter.

APO Nikkor 60cm F9 and Apo Nikkor 21cm F9

Apo-Nikkor lenses were specially designed for use in photo-engraving work and were available in a large range of focal length.
Both symmetrical and asymmetrical lenses were manufactured.
Nippon Kogaku offered several prisms and mirrors for this lenses for right-angle and with or without reversed image which were used as a single prism or mirror or in combination.

Apo Nikkor 60cm

This 60cm lens was manufactured in the late 1950's or early 1960's.
The style of the lens engraving is like the one used on Nikon rangefinder lenses.
At 1 : 1 reproduction ratio the image area is 80cm.
A brochure from 1960 (60.10.B) shows the same 60cm Apo-NIKKOR lens with a little different engraving

Ultra-Micro Nikkor 155mm F4

The Ultra-Micro-NIKKOR lenses were designed for the highest correction of aberration and sharpness for use to make photomasks.
The problem of designing the lenses of large aperture with highly corrected aberrations has been solved by limiting the range of wavelength of light to be used as a light source.
For that the Ultra-Micro-NIKKOR lenses were usually designed for a wavelength of 546.1 mμ(e-line).
Later lenses were manufactured for other wavelength as h-line with 404.7 mμ and g-line with 435.8 mμ.

The lenses have an extreme resolving power of 300 lines/mm for the 155mm lens up to 1.200 lines/mm for the 30mm lens. Of cause they were very high priced lenses at that time and represents the top of research and development for a lens manufacturer. This 155mm f/4 lens is extreme sharp, has 7 elements in 4 groups, an object area of 560mm and a weight of 1,090g.

Special Thanks Mr. Uli Koch
