This is an example of the kind of results we have obtained for each sample, with the numerical values and the graph of the transmitted wavelengths
We performed this work without any external financing.
Supporting this research would be for you a source of pride and for us it would mean a lot to be able to count on the contributions of people who are sensitive to the environmental issue.
If you want to help us carry out this research, for every donation of at least € 30.00, if you do not want to stay anonymous, we will send you a page similar to that of photography and related to the sample that you have contributed to finance.
A heartfelt thanks !!!
