• CIE Online Tutorial on the CIE L41 Reference Spectrum

  • When
    17 Nov 2026
  •  
    1:00 PM - 3:00 PM
  • Location
    Online (WebEx)

  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.

  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 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.
