CIE ONLINE TUTORIAL ON THE CIE L41 REFERENCE SPECTRUM
The CIE will hold an online tutorial on the CIE Reference Spectrum L41 on 17 November 2026, from 13:00 to 15:00 CET via Webex. The tutorial is organized by the CIE Division 2: Physical Measurement of Light and Radiation.
This two-hour tutorial will explain the need for an LED reference spectrum in the context of the transition from tungsten light sources to LED-based lighting. It will introduce the CIE 251:2023 LED Reference Spectrum for Photometer Calibration, describe its key properties, and present practical use cases in calibration, measurement, and simulation.
The tutorial will also provide guidance on implementing the reference spectrum in laboratory and industrial workflows, supporting broader adoption by photometry calibration laboratories, national metrology institutes, and manufacturers and users of photometric instruments.
For both CIE members and non-members, the tutorial offers special package pricing that includes access to the CIE 251:2023 LED Reference Spectrum for Photometer Calibration publication as part of the registration fee, making it a particularly valuable opportunity to obtain both expert training and the publication together.
This online tutorial will be particularly useful for photometry calibration laboratories, including national metrology institutes, as well as manufacturers and users of photometric instruments who are working with LED-based lighting, calibration, measurement, or simulation.
The registration is expected to open in September.

Further information about the online tutorial, including the programme and pricing packages, is available on the CIE website.
CIE TUTORIAL ON MONTE CARLO METHOD FOR UNCERTAINTY ANALYSIS
The CIE Tutorial on Monte Carlo Method for Uncertainty Analysis is organized by CIE NC Korea and CIE Division 2: Physical Measurement of Light and Radiation, in conjunction with the 16th International Conference on New Developments and Applications in Optical Radiometry (NEWRAD 2026).
The tutorial will take place at the Seogwipo KAL Hotel in Jeju Island, South Korea, on 17 September 2026, following the conclusion of NEWRAD 2026. The tutorial will start at 13:00 and conclude at 18:00 Korea Standard Time (UTC+9). The CIE Division 2 Annual Meeting will take place on 18 September 2026, from08:30 to 12:00 Korea Standard Time (UTC+9), at the same venue. Meetings of several CIE Division 2 Technical Committees will follow after the Annual Meeting.
The will present the principles and practical applications of the Monte Carlo method for uncertainty analysis in photometry and radiometry, with reference to CIE 198:2011 Determination of Measurement Uncertainties in Photometry and its supplements CIE 198-SP1.1:2011 Modules for the Construction of Measurement Equations and CIE 198-SP1.2:2011 Examples for Models with Individual Inputs. The tutorial provides both theoretical background and practical guidance, supporting professionals in strengthening their understanding of uncertainty evaluation in line with established CIE publications.
The tutorial offers valuable insights and is particularly relevant for professional working in photometry and radiometry, including photometry calibration laboratories (such as National Metrology Institutes), testing laboratories in photometry, radiometry, and colorimetry, as well as manufacturers and users of photometric and radiometric instruments.
The registration system is expected to open on 15 June 2026.
