FR Nikkor 75mm F1.0 Specifications
Nikkor, Nippon Kogaku, BAOL 6503-69, September 1966
FR-Nikkor lens has been designed exclusively for life-size photography (1:1) in 35mm format.
Features of FR-Nikkor
The FR-Nikkor lens has been designed for full-size reproduction of subjects.
On the other hand, the FR-Nikkor lens has a maximum aperture ratio of f/1 (Effective aperture ratio f/2), and the optical system comprises 8 symmetrically arranged elements in 6 groups, which corrects all the aberrations.
Until now, the Micro-Nikkor has topped the list of close-up lenses in brightness and resolution.
However, due to the high speed and correction of aberrations in the lens,
magnification is limited within the practical range of 0.9X-1.1X.
This feature gives FR-Nikkor lens a great advantage when used as a relay lens and enables taking over of the image relayed from a front lens system and producing a full-size image of the subject.
Entrance Pupil, Exit Pupil and Luminous Flux
Being a full-size and extremely bright lens, the FR-Nikkor is ideal for the following purposes:
1. For recording the phenomena under poor lighting conditions, or for taking close-ups of subjects moving rapidly on an electron tube or the like.
For reproduction of images taken on the film of high resolution.
The FR-Nikkor lens enables reproduction of the image in detail even
when it is captured on a fine-grained film.
3. For use as a relay lens. With FR-Nikkor lens, it is possible to receive almost all the rays from a front lens system without using a condenser lens, as light beams coming through the FR-Nikkor lens run parallel to the optical axis and the aperture is f/1.
The conventional type of lens,
where the entrance pupil is located near the center of the lens system,
would require a powerful condenser lens which would result in some distortion of the image plane,
in lowering the resolution of the lens system.
When using the lens as a relay lens,
it is necessary to take into consideration the relationship of the optical systems
in front and back of the lens.

What is AR?
Do you know the meaning of AR of AR 1:2?
When you put an irresponsible guess article in the internet, someone believes that it is truth. That incorrect information will propagate instantaneously all over the world.
AR is the abbreviation of effective Aperture Ratio
When I was investigating the technical material "REPRO - NIKKOR LENSES", I found that the meaning of the abbreviation of AR is described. AR is the abbreviation of effective Aperture Ratio.
