Calibration of Raman Spectrometers
Accurate Raman spectroscopy relies on precise wavelength and intensity measurements, making regular calibration essential. Calibration ensures that the spectrometer correctly assigns Raman shifts and maintains reproducible spectral responses, which is critical for identifying materials and comparing results across instruments. Standard reference materials, such as silicon or naphthalene, are commonly used because their Raman peaks are well-defined and stable. By calibrating both the wavelength axis and detector sensitivity, operators can minimize instrumental errors, improve spectral resolution, and enhance the reliability of quantitative and qualitative analyses. Routine calibration is a cornerstone of high-quality Raman spectroscopy in research and conservation.
Learn Technical Photography for Art Examination
Technical Photography is one of the most powerful—and often overlooked—tools for the scientific examination of art and archaeology. If you are a conservator, scientist, or art collector and you are not yet familiar with this method, it is truly a missed opportunity. Using simple, affordable equipment and a clear methodology, Technical Photography allows you to reveal underdrawings, retouchings, material differences, and conservation issues in a completely non-invasive way. Far from being complex or inaccessible, it is an easy entry point into scientific analysis. In many cases, Technical Photography represents the first essential step toward a deeper understanding of artworks and archaeological objects.
