Foreword

ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.

The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).

Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of any patent rights identified during the development of the document will be in the Introduction and/or on the ISO list of patent declarations received (see www.iso.org/patents).

This document was prepared by Technical Committee ISO/TC 172, Optics and photonics, Subcommittee SC 4 Telescopic systems.

This second edition cancels and replaces the first edition (ISO 14490‑5:2005), which has been technically revised. It also incorporates the ISO 14490‑5:2005/Amd 1:2015.

The main changes are as follows:

— the normative references has been updated;
— In 5.8, the wording has been changed to "maximum diameter of the aperture stop";
— Formulae (3) and (4) have been corrected.

A list of all parts in the ISO 14490 series can be found on the ISO website.
