UV-C lamp measurements principles and typical applications (GL Optic)
Theory and practical examples of UV applications:
Due to the pandemic, we witness significant increase in the demand for the UVC disinfection lamps. This, in turn, requires reliable measurement methods and instruments to verify the performance parameters of lamps and systems.
This presentation will include an introduction to the principles of the UV source measurements and available methods for full characterization of UV-C lamps and systems. The safety issues will be discussed along with the physics of UV optical radiation and the proper use of measuring devices will be discussed.

Measurements of UVC devices for disinfection – discussion on practical aspects and limitations of characterizing UVC luminaires:
Rapidly increasing demand for  UVC based applications for disinfection purposes has faced gaps and pitfalls in common practical approach  in terms of performance characterisation and validation. There are no standardised equivalents to photometric files applicable for UV radiant intensity, no tools for  practical  assessment of UVC reflection and degradation properties of materials, no clear requirements for spectral range and devices used for measurements as well as calculating  required UVC radiant flux or irradiance based on measured results.  Both measurement and designing field applications of UVC devices encounter  pitfalls. Discussion will aim to share common practice and discuss doubts and potential limitations for practitioners measuring and designing installations for UVC air or surface disinfection.

CARLO – Calibration and Research Laboratory of Optical Radiation (GL Optic)
The Black Body radiator at CARLO:
The presentation of Calibration and Research Laboratory of Optical Radiation (CARLO) will cover the main issues related to calibration of array spectroradiometers including the procedure of detector response linearization in a wide dynamic range. The organisation of optical calibration laboratory with the high-temperature blackbody radiator as a primary spectral standard as well as calibration of new standards with reference to the primary standard will also be discussed. Equipment designed and built for these purposes will be presented.

Practical application of Luminance Distribution Measurements of Road Lighting according to the EN 13201: 2016 standard. (Poznan University of Technology)
Theoretical introduction and comparison results:
The verification of the road lighting quality by the luminance method complies with the EN 13201: 2016 standard recommendation: Road lighting. However, practice shows that road luminance distribution measurements are rarely performed. Among the reasons, there is the lack of appropriate measuring devices designed and prepared for the field measurements, which support the rapid execution of accurate and repeatable measurements. The presentation presents the assumptions of the luminance method used to assess the quality of lighting for roads intended mainly for motorised traffic from medium to high speed. The main part of the presentation concerns the issues of measuring luminance distributions on roads. Examples of measurements made on the expressway are presented. Moreover, the likely reasons for the differences between the project results and the measurement results are described.

Practical live presentation:
Live presentation of the new Imaging Luminance Measuring Device adapted to the field measurements in accordance with EN 13201: 2016 Road Lighting standard. This work was a subject of research and development project developed in cooperation between GL Optic and Poznan University of Technology, co-financed by National Research and Development Centre. The presentation will cover a step-by-step system setup from the transportation state to the measurement ready state. It will feature details of the measurement process itself including parameters setting, image analysis and calculation of the road lighting results as per Road Lighting Standard up to the report sheet generation.
