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).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and
expressions related to conformity assessment, as well as information about ISO's adherence to
the World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT), see

This document was prepared by Technical Committee ISO/TC 172, Optics and Photonics, Subcommittee
SC 9, Laser and electro-optical systems, in collaboration with the European Committee for Standardization
(CEN) Technical Committee CEN/TC 123, Lasers and photonics, in accordance with the agreement on
technical cooperation between ISO and CEN (Vienna Agreement).
This second edition cancels and replaces the first edition (ISO 24013:2006), which has been technically
revised.
The main changes are as follows:
— 6.3.3 was amended to add an additional step requiring that a transmitting optic be aligned so that
its optical axis is horizontal;
— Clauses 2 and 6.1 were amended to reflect that ISO 14644-1:1999 does not need the year;
— 6.3.1, (π/4 ± 2) mrad was changed to π/4 rad ± 2 mrad;
— 7.1 and 8.1 were updated to account for phase retardances close to π.
Any feedback or questions on this document should be directed to the user’s national standards body. A

Introduction
Normally it is desirable that the state of polarization be not influenced by the optical components used.
For the generation or maintenance of specific states of polarization the influence of optical components
on the beam polarization is crucial. For generating circularly polarized radiation from linearly polarized
radiation π/2 phase retarders are used.
This document describes methods to determine the relative phase retardation of optical components
with respect to the X- and Y-axes of the polarization and s- and p-polarization, respectively. This
document is necessary for optics manufacturers, suppliers and customers of such optics for the
determination of the influence of phase retardation of optical components.

5 Measurement principle
The optical component under test is irradiated by a laser beam with a defined state of polarization.
After passing the component the state of polarization of the beam is determined by using an analyser.
The phase retardation is then evaluated from the change of the state of polarization.
There are two cases to distinguish:
a) the expected phase retardation is near zero: in this case a circularly polarized beam shall be used
for the test;
b) the expected phase retardation is near π/2: in this case a linearly polarized beam shall be used for
the test.
Figure 1 shows the measuring set up.
a) Optical path for reflective samples
b) Optical path for transmissive samples

Figure 1 — Schematic drawing of the measuring set up
A laser and a polarizer generating linearly or circularly polarized radiation shall be used in combination
with an analyser and a power detector. For measuring reflective samples an alignment laser in
combination with a positional sensitive detector ensures a reproducible angle alignment of the sample
under test.
