One of the often discussed themes is so called “light pollution“. A long time we participate in research in this area and we have a direct experience with a lot of measurement of the night sky, night city background, and luminance analyses. 

With luminance meter LumiDISP – LDA ML7 you are able to measure so small luminance, as you cannot see by eye – in levels below 0,001 cd.m-2. It can be very useful for checking light in protected natural areas, parks and zones, where light pollution should be limited.

In the period 2022 – 2024, we have been involved in research on methods for the assessment of artificial light in the night environment. A unique measurement system was developed, the output of which will be a methodology for the assessment of artificial light in the night environment. We are waiting for the approval of the methodology, but a prototype of the instrument has been created and it is yielding very interesting results. Here again, we use digital camera technology supplemented by special adaptations, software algorithms and methods to obtain the necessary indicators.
