This document specifies methods for measuring beam widths (diameter), divergence angles and beam propagation ratios of laser beams. This document is applicable to general astigmatic beams or unknown types of beams. For stigmatic and simple astigmatic beams, ISO 11146‑1 is applicable. Within this document, the description of laser beams is accomplished by means of the second order moments of the Wigner distribution rather than physical quantities such as beam widths and divergence angles. However, these physical quantities are closely related to the second order moments of the Wigner distribution. In ISO/TR 11146‑3, formulae are given to calculate all relevant physical quantities from the measured second order moments.

This document specifies measurement procedures for the precise determination of the high reflectance or high transmittance (>99 %) of optical laser components. The methods given in this document are intended to be used for the testing and characterization of high reflectance of both concave and plane mirrors or high transmittance of plane windows used in laser systems and laser-based instruments. The reflectance of convex mirrors or transmittance of positive or negative lenses can also be tested by taking into consideration the radius of curvature of the mirror surface or the focal length of the lens. This document is complementary to ISO 15368 which specifies the measurement procedures for the determination of reflectance and transmittance of optical components with spectrophotometry. ISO 15368 is applicable to the measurements of reflectance and transmittance in the range from 0 % to 100 % with a typical accuracy of ±0,3 %, and is therefore not applicable to the precise measurements of reflectance and transmittance higher than 99,9 %.

IEC 60825-2:2021 provides requirements and specific guidance for the safe operation and maintenance of optical fibre communication systems (OFCSs). In these systems, optical power is possibly accessible outside the confines of the transmitting equipment and/or at great distance from the optical source.
This document requires the assessment of hazard level at each accessible location of the OFCS as a replacement for product classification according to IEC 60825-1. It applies to the installed OFCS as an engineered, end-to-end assembly for the generation, transfer and receipt of optical radiation arising from lasers, light-emitting diodes (LEDs) or optical amplifiers, in which the transference is by means of optical fibre for communication and/or control purposes.
Individual components and subassemblies that fall under the definition of a laser product are subject to the applicable subclause(s) of IEC 60825-1. This document is applicable to individual components and subassemblies intended to be installed within OFCSs.
This document does not apply to optical fibre systems primarily designed to transmit optical power for applications such as material processing or medical treatment.
In addition to the hazards resulting from laser radiation, OFCSs possibly give rise to other hazards, such as fire.
This document does not address safety issues associated with explosion or fire with respect to OFCSs deployed in explosive atmospheres.
This fourth edition cancels and replaces the third edition published in 2004, Amendment 1:2006 and Amendment 2:2010. This edition constitutes a technical revision.

IEC 62977-2-1:2021(E) specifies standard measurement conditions and measuring methods for determining the optical characteristics of electronic display modules and systems. These methods apply to emissive and transmissive direct view displays that render real 2D images on a flat panel. This document evaluates the optical characteristics of these displays under darkroom conditions. This document applies to the testing of display performance in response to standard analogue or digital input signals that are not absolute luminance encoded. The input signal is relative RGB without metadata information that codes for real luminance, colour space or colour coordinates. These methods are limited to input signals with typical OETFs such as defined in IEC 61966-2-1, ITU BT. Rec. 601, ITU BT. Rec.709, and ITU BT. Rec.2020. The tests in this document are not approved for use with HDR input signals.
NOTE A flat panel or flat panel display is a display with a flat surface and minimal depth that emits visible light from the surface. The display is subdivided into an array of electronically driven pixels which can be light valves modulating a backlight, or self-luminous. Emissive/transmissive/reflective hybrid displays can be flat panel or flat panel displays.

This part of IEC 61496 specifies general requirements for the design, construction and testing
of non-contact electro-sensitive protective equipment (ESPE) designed specifically to detect
persons or part of a person as part of a safety-related system. Special attention is directed to
functional and design requirements that ensure an appropriate safety-related performance is
achieved. An ESPE can include optional safety-related functions, the requirements for which
are given in Annex A.
NOTE "Non-contact" means that physical contact is not required for sensing.
This document is intended to be used with a subsequent part of IEC 61496 that provides
particular requirements based on the sensing technology.
EXAMPLE This document and IEC 61496-2 are used for AOPDs; this document and IEC 61496-3 are used for
AOPDDRs.
Where a part covering the sensing technology does not exist, IEC TS 62998-1 is used.
Where the IEC 61496 series does not contain all necessary provisions, IEC TS 62998-1 is
used.
It is an additional possibility to combine those aspects covered by the IEC 61496 series in
addition to IEC TS 62998-1.
This document does not specify the dimensions or configuration of the detection zone and its
disposition in relation to hazards in any particular application, nor what constitutes a
hazardous state of any machine. It is restricted to the functioning of the ESPE and how it
interfaces with the machine.
While a data interface can be used to control optional safety-related ESPE functions
(Annex A), this document does not provide specific requirements. Requirements for these
safety-related functions can be determined by consulting other standards (for example,
IEC 61508 (all parts), IEC 62046, IEC 62061, and ISO 13849-1).
This document can be relevant to applications other than those for the protection of persons,
for example for the protection of machinery or products from mechanical damage. In those
applications, different requirements can be appropriate, for example when the materials that
have to be recognized by the sensing function have different properties from those of
persons.
This document does not deal with requirements for ESPE functions not related to the
protection of persons (e.g. using sensing unit data for navigation).
This document does not deal with electromagnetic compatibility (EMC) emission
requirements.

This part of EN 60825 provides requirements and specific guidance for the manufacture and safe use of laser products and systems used for point-to-point or point-to-multipoint free space optical data transmission. This standard only addresses the open beam portion of the system. If portions of the equipment or system incorporate optical fibre that extends from the confinements of the enclosure(s), the manufacturing and safety requirements under EN 60825-1 apply to those portions only. This standard does not apply to systems designed for purposes of transmitting optical power for applications such as material processing or medical treatment. This standard also does not apply to the use of systems in explosive atmospheres. The objective of this part of EN 60825 is to: - provide information to protect people from potentially hazardous optical radiation produced by free space optical communication systems (FSOCS) by specifying engineering controls and requirements, administrative controls and work practices according to the degree of the hazard; - specify requirements for manufacturing, installation, service and operating organisations in order to establish procedures and provide written information so that proper precautions can be adopted.

IEC TR 62595-1-3:2019 (E) focuses on common issues of light emission such as spatial uniformity of luminance and colour, and angular distribution of luminance and colour, from lighting units with arbitrary shapes like flexible lighting sources (FLSs). This document provides a model of light emission from a curved FLS and of light measurement on a curved FLS. Because the development of flexible liquid crystal panels is in progress (see the notes), the intent of this document is to provide guidance for the development of future measurement standards. This document is applicable to FLSs either as light sources, products or elements with arbitrary shapes of geometrical curvature having different spectral and spatial characteristics of light emission.
NOTE 1 Almost 20 years ago plastic LCDs were developed and used in a few applications.
NOTE 2 Flexible BLUs have been used for bendable LC panels in recent years.
NOTE 3 Recent transmissive and transflective flexible LCs require flexible BLUs.

This part of IEC 61496 specifies additional requirements for the design, construction and
testing of electro-sensitive protective equipment (ESPE) designed specifically to detect
persons or parts of persons as part of a safety-related system, employing active optoelectronic
protective devices responsive to diffuse reflection (AOPDDRs) for the sensing
function. Special attention is directed to requirements which ensure that an appropriate
safety-related performance is achieved. An ESPE can include optional safety-related
functions, the requirements for which are given both in Annex A of this document and in
Annex A of IEC 61496-1:2012.
This document does not specify the dimensions or configurations of the detection zone and its
disposition in relation to hazardous parts for any particular application, nor what constitutes a
hazardous state of any machine. It is restricted to the functioning of the ESPE and how it
interfaces with the machine.
AOPDDRs are devices that have either
– one or more detection zone(s) specified in two dimensions (AOPDDR-2D), or
– one or more detection zone(s) specified in three dimensions (AOPDDR-3D)
wherein radiation in the near infrared range is emitted by an emitting element(s). When the
emitted radiation impinges on an object (for example, a person or part of a person), a portion
of the emitted radiation is reflected to a receiving element(s) by diffuse reflection. This
reflection is used to determine the position of the object.
Opto-electronic devices that perform only a single one-dimensional spot-like distance
measurement, for example, optical proximity switches, are not covered by this document.
This document does not address those aspects required for complex classification or
differentiation of the object detected.
This document does not address requirements and tests for outdoor application.
Excluded from this document are AOPDDRs employing radiation with the peak of wavelength
outside the range 820 nm to 950 nm, and those employing radiation other than that generated
by the AOPDDR itself. For sensing devices that employ radiation of wavelengths outside this
range, this document can be used as a guide. This document is relevant for AOPDDRs having
a minimum detectable object size in the range from 30 mm to 200 mm.
This document can be relevant to applications other than those for the protection of persons,
for example, for the protection of machinery or products from mechanical damage. In those
applications, different requirements can be appropriate, for example when the materials that
have to be recognized by the sensing function have different properties from those of persons
and their clothing.
This document does not deal with electromagnetic compatibility (EMC) emission requirements.
