Geometrical product specifications (GPS) - Surface texture: Areal - Part 602: Design and characteristics of non- contact (confocal chromatic probe) instruments (ISO 25178-602:2025)
This document specifies the design and metrological characteristics of a particular non-contact instrument for measuring surface texture using a confocal chromatic probe based on axial chromatic aberration of white light. Additional metrological characteristics can be found in ISO 25178-600. Because surface profiles can be extracted from areal surface topography data, the methods described in this document are also applicable to profiling measurements.

Dieses Dokument legt die Konstruktion und metrologischen Merkmale eines berührungslos messenden Geräts zur Messung der Oberflächentopographie fest, welches eine chromatisch konfokale Sonde verwendet, deren Funktion auf der axialen chromatischen Aberration von weißem Licht beruht. Zusätzliche messtechnische Merkmale können ISO25178-600 entnommen werden. Da Oberflächenprofile aus Daten von Oberflächento
pographien extrahiert werden können, können die meisten Verfahren, die in diesem Dokument festgelegt sind, auch auf Profilmessungen angewendet werden.

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

Introduction
This document is a geometrical product specification (GPS) standard and is to be regarded as a general
GPS standard (see ISO 14638). It influences chain link F of the chains of standards on profile and areal
surface texture.
The ISO GPS matrix model given in ISO 14638 gives an overview of the ISO GPS system of which this
document is a part. The fundamental rules of ISO GPS given in ISO 8015 apply to this document and
the default decision rules given in ISO 14253-1 apply to the specifications made in accordance with this
document, unless otherwise indicated.
For more detailed information of the relation of this document to other standards and the GPS matrix
model, see Annex C.
The confocal chromatic optical principle can be implemented in various set-ups. The configuration
described in this document comprises three basic elements: an optoelectronic controller, a linking fibre
optic cable and a chromatic objective (sometimes called “optical pen”).
Several techniques are possible to create the axial chromatic aberration or to extract the height
information from the reflected light. In addition to implementations as point sensors, chromatic
aberration can be integrated into line sensors and field sensors. Annex A describes in detail confocal
chromatic imaging and its implementation into distance measurement probes.
This type of instrument is mainly designed for areal measurements, but it is also able to perform profile
measurements.
This document describes the metrological characteristics of an optical profiler using a confocal
chromatic probe based on axial chromatic aberration of white light, designed for the measurement of
areal surface texture.
For more detailed information on the chromatic probe instrument technique, see Annex A. Reading this
annex before the main body can lead to a better understanding of this document.
NOTE Portions of this document, particularly the informative sections, may describe patented systems and
methods. This information is provided only to assist users in understanding the operating principles of confocal
chromatic probe. This document is not intended to establish priority for any intellectual property, nor does it
imply a license to proprietary technologies described herein.

1 Scope
This document defines the design and metrological characteristics of a particular non-contact
instrument for measuring surface texture using a confocal chromatic probe based on axial chromatic
aberration of white light. Additional metrological characteristics can be found in ISO 25178-600.
Because surface profiles can be extracted from areal surface topography data, the methods described
in this document can be applied to profiling measurements as well.
