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 second edition cancels and replaces the first edition (ISO 14880-3:2006), which has been
technically revised.
The main changes are as follows:
— Introduction revised.
— Reference documents and numbering updated.

Introduction
This document specifies methods of testing optical properties, other than wavefront aberrations, of
microlens arrays. Examples of applications for microlens arrays include three-dimensional displays,
coupling optics associated with arrayed light sources and photo-detectors, enhanced optics for liquid
[12][13][15][16]
crystal displays, and optical parallel processor elements .
The testing of microlenses is in principle similar to testing any other lens. The same parameters need
to be measured and similar techniques used. However, in many cases the measurement of very small
lenses presents practical problems which make it difficult to use the standard equipment that is
[15][16]
available for testing normal size lenses .
The market in microlens arrays has generated a need for agreement on basic terminology and test
methods. Standard terminology and clear definitions are needed not only to promote applications
but also to encourage scientists and engineers to exchange ideas and new concepts based on common
understanding.
This document contributes to the purpose of the series of ISO 14880 standards which is to improve the
compatibility and interchangeability of lens arrays from different suppliers and to enhance development
of the technology using microlens arrays.
Characteristic parameters are defined and examples of applications given in ISO 14880-1, Vocabulary.
It has been completed by a set of three other International Standards, i.e. Part 2, Test methods for
wavefront aberrations, Part 3, Test methods for optical properties other than wavefront aberrations and
Part 4, Test methods for geometrical properties.
This document describes the measurement of 1) focal length, 2) coupling efficiency, 3) imaging quality
and 4) focal spot positions.
The focal length of the microlens is defined more precisely in 14880-1 as effective back (front) focal
length.
The measurement of effective back (front) focal length is described in the body of this part of ISO 14880
and the use of an alternative technique, interferometry, is described in Annex A.
Measurement of the focal length of an array of microlenses, using a confocal technique, is described in
the main body and Annex B.
Coupling efficiency and imaging quality are discussed in Annex C.
Measurement of the focal spot positions of an array of microlenses in parallel, using the Shack-Hartmann
technique, is described in Annex D.
Wavefront aberrations and characteristics other than optical properties are specified in ISO 14880-2
and ISO 14880-4 and ISO/TR 14880-5.
