Micro Nikkor 70mm F5 Lens Specifications

MICRO-NIKKOR LENSES

Micro-Nikkor lenses are designed for making microphotographs or micro-copies.
According to the size of the micro-film, four types of Micro-Nikkor lenses are available.
The term microphotography means the photographic and various related techniques of reproducing printed or other graphic matters into a small photograph of extreme reducion ratio so the reproduced version cannot be read or discriminated with the naked eyes and is normally magnified for viewing.

In general, microphotophy indicates printed and other graphic matters of scale being systematically reproduced on micro-films in large quantities.
These optically reduced information materials can be easily enlarged to their original sizes through micro-readers, enlargers etc., or office duplicators equipped to these equipments for perusal and reproduction.

The adoption of this microcopying process considerably cuts down the volume and weight of information materials to be stored and thus, greatly contributes to the economizing of storage space, facilitating of transportation and also providing convenience in classification, controlling and long period storage.

Due to these mentioned reasons, this process is being widely used today for the rationalization of office work concerning stogage of information materials.
Microphotographs, due to their nature, are required to use a film of fine grain possessing high resolving power and a lens having an extremely high resolution over the entire image area as it is necessary to faithfully reproduce every minor detail of the subject matters.

Features of Micro-Nikkor

Micro-Nikkor lenses possess extremely high resolving power of producing superior microphotographs.
A modified Gauss type 4 groups and 5 elements (Japanese Patent No. 221051).
Since this lens is designed mainly for capability without being avaricious on apertute ratio, it produces a clear and distinct image.
The big difference between ordinary and micro lenses lies in their standard reduction ratio.
Ordinary lenses are generally designed for objects at infinitie distance, whereas, the micro-lenses are designed for use under satandard reduction ratios.
Therefore, although ordinary lenses may be suitable for photographing, their capability is not assured for reproduction and close-up.

The Micro-Nikkor lenses have been basically designed for precise reproduction and possess even flatness of images suited for reproduction and close-up.
In addition, astigmatism abberration has been corrected to the maximum extent and variation due to change of reduction ratio does not occur.
The diameter of the front and rear lens groups has been designed larger than the indicated apertures, so the lens gives an ample share of light throughout the corners of the picture and prevents uneven exposures.

Application

Micro-Nikkor lenses possess superior capabilities.
But, in case of close-up photography, special consideration must be given on focusing and the film plane must be parallel to the original negative due to its shallow depth of focus.
When making use of the lens capability to extreme extents, it is necessary to prepare special purpose equipment.
