Spectral Responsivity Measurement of Detectors, Radiometers and Photometers

This Technical Report gives recommendations for spectral radiant power, irradiance and radiance responsivity measurement of single element detectors in the 200 nm to 2 500 nm wavelength range. It covers measurement setups and methods, summarizes the types and basic properties of typical detectors, radiometers and photometers and gives guidance on how to choose a reference detector. Spectral considerations for source and radiometer applications, detector amplifier application issues and measurement uncertainties are described. Primary detector standards and procedures for the realization of units and responsivity functions are the responsibility of national metrology institutes and are not discussed in this report. This Technical Report was written to update Technical Report CIE 64-1984 “Determination of the Spectral Responsivity of Optical Radiation Detectors” with respect to device and measurement technology, and to include spectral irradiance and radiance responsivity measurements for radiometers and photometers from the ultraviolet wavelength range up to 2 500 nm.

This publication supersedes CIE 64-1984 “Determination of the Spectral Responsivity of Optical Radiation Detectors”.

The publication is written in English, with a short summary in French and German. It consists of 82 pages with 41 figures and is readily available at the National Committees of the CIE or at the web shop of the CIE (www.techstreet.com/cgi-bin/joint.cgi/cie).

Recommendations on Minimum Levels of Solar UV Exposure

The Proceedings of the 27th Session of the CIE comprise two volumes.

This Technical Report addresses the issue of sensible exposure to solar ultraviolet (UV) radiation. The scientific evidence of beneficial effects of solar exposure has been reviewed, in particular on the incidence and mortality to cancers other than skin cancer. Although the evidence is not unequivocal, the committee has found considerable evidence to deem it plausible that solar exposure may reduce the incidence and mortality of colorectal cancer. The evidence for similar effects on breast and prostate cancer and on melanoma is less, but such effects are considered as plausible, too. Possibly the production of vitamin D plays a role in this respect.

Based on a review of the evidence of both the beneficial and the harmful effects of solar exposures it is concluded that people should not shun the sun, even not at noon. However, levels well below sunburn thresholds are generally sufficient to profit from the beneficial effects of solar exposure. Public health guidance should be developed on the basis of this evidence, but account should also be taken of prevailing solar UV levels that depend on latitude and time of the year and day. Special guidance may be necessary for dark skinned people that live at moderate latitudes and people that cover most of their bodies for cultural or religious reasons. The same holds for people who stay most of the time indoors.

The amount of solar exposure commensurate with good health depends on individual and population characteristics, as indicated above. To facilitate public health guidance it is recommended to extend the concept of the UV index promulgated by the World Health Organization to include the beneficial effects of solar exposure.

The report is split into two parts: The first part (Part I) gives guidance for a sensible exposure regime to profit from beneficial health impacts from moderate solar (UV) exposure, the second part (Part II) is a review of scientific data that underpin the guidance in Part I.

The publication is written in English, with a short summary in French and German. It consists of 88 pages with 4 figures and 20 tables and is readily available at the National Committees of the CIE or at the web shop of the CIE (www.techstreet.com/cgi-bin/joint.cgi/cie).

The price of this publication is EUR 108,-.

CIE Supplementary System of Photometry

The CIE Supplementary System of Photometry, which evaluates lights in terms of comparative brightness relationship at any level, is described. The system introduces the concept of equivalent luminance to describe brightness of a light or an object at any level including mesopic levels. The system develops a photometric model to calculate brightness-related equivalent luminance by using three components of existing photometric and colorimetric quantities (photopic luminance, L, scotopic luminance, LŚ, and chromatic contribution to brightness, c, i.e. brightness-to-luminance ratio (B/L)) with some weighting factors in their combinations that depend on the adaptation level. The use of the system and an example of calculation are also described. Results of testing the system with experimental brightness matching data are given in an appendix.

The publication is written in English, with a short summary in French and German. It consists of 21 pages with 5 figures and 1 table and is readily available at the National Committees of the CIE or via the website of the Central Bureau of the CIE (www.cie.co.at).

CIE Standard S 017/E:2011
ILV: International Lighting Vocabulary

CIE has published Standard CIE S 017/E:2011 ILV: International Lighting Vocabulary.

This new edition of the International Lighting Vocabulary (ILV) is the result of intensive work carried out by the Divisions of the CIE to update, and supplement where necessary, the contents of the previous edition (1987). Many new terms have been added, to reflect changes in technologies and practices, existing terms have been updated as necessary, and obsolete terms have been removed.

The aim of this edition of the International Lighting Vocabulary is to promote international standardization in the use of quantities, units, symbols and terminology related to the science and art of light and lighting, colour and vision, photobiology and image technology. This vocabulary provides the definitions and essential information necessary for the understanding and correct usage of the terms included. It does not give extensive detail or explanations of the application of these terms; such information, relevant for experts in each specialized field, is available in the Technical Reports and Standards produced by the CIE.

For this new edition it was decided to restructure the vocabulary to a fully alphabetical arrangement (based on the English terms), without any division into sections or sub-sections. This decision was taken in order to simplify the ILV and aid its use.

The Standard comprises 203 pages and presents the definitions of 1448 terms related to light and lighting. It is readily available at the National Committees of the CIE or via the website of the Central Bureau of the CIE (www.cie.co.at).

Price of this Standard: EUR 297,-

Colorimetry - Part 3: CIE Tristimulus Values

CIE Standard S 014-3/E:2011

Colour stimuli with different spectral distributions can look alike. An important function of colorimetry is to determine which stimuli look alike to a given observer with a given set of colour-matching functions. This is done by calculating a set of three tristimulus values for each stimulus. Equality of tristimulus values indicates equality of colour appearance under equal irradiation and viewing conditions. This Standard is based on long-standing CIE recommendations (CIE15:2004 Colorimetry, 3rd edition) for the calculation of tristimulus values. It specifies methods of calculating the tristimulus values of colour stimuli for which the spectral distributions are provided. These colour stimuli may be produced by self-luminous light sources or by reflecting or transmitting objects.

The standard method is defined as summation at 1 nm intervals over the wavelength range from 360 nm to 830 nm. Alternative abridged methods are defined for larger intervals (up to 5 nm) and shorter ranges (down to 380 nm to 780 nm). The alternative methods are to be used only when appropriate and when the user has reviewed the impact on the final results.

The Standard may be used in conjunction with the CIE 1931 standard colorimetric observer or the CIE 1964 standard colorimetric observer.

The Standard has been approved by the CIE National Committees. It is readily available at the National Committees of the CIE or via the website of the Central Bureau of the CIE (www.cie.co.at).

CIE Guide to increasing accessibility in Light and Lighting

CIE 196:2011 ISBN 978 3 901906 94 7

This guide was written for lighting designers and engineers, as well as scientists of light, colour, and vision to assist them in taking account of the needs of older persons and persons with disabilities. The guide was developed in accordance with ISO/IEC Guide 71:2001 “Guidelines for standard developers to address the needs of older persons and persons with disabilities” and its technical guidelines ISO/TR 22411:2008 “Ergonomics data and guidelines for the application of ISO/IEC Guide 71 to products and services to address the needs of older persons and persons with disabilities” in order to implement accessible design in the field of light and lighting. Some content has been shared with those two documents. The guide was prepared by a Working Group (Ad-hoc) in the CIE Board of Administration in cooperation with TC 1-54 “Age-related change of visual response” and TC 3-44 “Lighting for the elderly”.

The publication is written in English, with a short summary in French and German. It consists of 63 pages with 20 figures and 11 tables and is readily available at the National Committees of the CIE or via the website of the Central Bureau of the CIE (www.cie.co.at).

Specification of Colour Appearance for Reflective Media and Self-Luminous Display Comparisons

Background Information Relating to the Development of the CIECAM02 Colour Appearance Model

CIE 195:2011 ISBN 978 3 901906 93 0

This Technical Report summarizes the body of work conducted by CIE Technical Committee 1-27 “Specification of Colour Appearance for Reflective Media and Self-Luminous Display Comparisons” from 1990 until 2001. After compiling data from researchers around the world and studying various forms of colour appearance models to predict results from hardcopy/softcopy matching experiments under a variety of viewing conditions, it was discovered that the same colour appearance model would not consistently or adequately predict the visual results. In 2001, all CIE TC1-27 results were passed along to CIE TC 8-01, Colour Appearance Modeling for Colour Management Systems. This Technical Committee within Division 8 formulated an effective colour appearance model by combining the best features of the colour appearance models that were studied by CIE TC1-27. The result was the development of the CIECAM02 colour appearance model.

The publication is written in English, with a short summary in French and German. It consists of 46 pages with 28 figures and 14 tables and is readily available at the National Committees of the CIE or via the website of the Central Bureau of the CIE (www.cie.co.at).

The price of this publication is EUR 66,--

On Site Measurement of the Photometric Properties of Road and Tunnel Lighting

CIE 194:2011 ISBN 978 3 901906 92 3

This Technical Report gives the information which designers and users of automatic systems intended to measure the photometric properties of road and tunnel lighting systems need in order to understand the performance of such systems. The main aim of this guide is to clearly define and describe the technical limitations and characteristics of these measurement systems. In this way the advantages and disadvantages of the technical solutions adopted in different systems can be assessed. Their measurement uncertainty can be evaluated and discrepancies understood when the measurement results are compared with those obtained by manual systems or by theoretical evaluations from mathematical algorithms and/or computer simulations. The guide concentrates on systems that measure horizontal illuminance and luminance on road surfaces but much of the guidance is relevant to other quantities and measurement conditions. The guide is divided into two parts:

  • Review of essential photometric quantities where differences between their physical or normative definition, their mathematical evaluation and their measurable approximation are highlighted (Clause 2 and Clause 3);
  • Review of the types and characteristics of instruments, the conditions and methodologies of measurements, the evaluation of uncertainty in measurement results and data elaboration (Clause 5, Clause 6 and Clause 7).
    The publication is written in English, with a short summary in French and German. It consists of 90 pages with 45 figures and 6 tables and is readily available at the National Committees of the CIE or via the website of the Central Bureau of the CIE (www.cie.co.at).

The publication is written in English, with a short summary in French and German. It consists of 90 pages with 45 figures and 60 tables, and is readily available at the National Committees of the CIE or via the website of the Central Bureau of the CIE (www.cie.co.at).
