Miniature spectrometers address challenges of LED research and production (MAGAZINE)
Miniature, portable spectrometer systems can provide accurate in-situ measurements and analysis of LED light sources for a variety applications, including horticulture, according to Jason Eichenholz, Marco Snikkers and Dennis Schulmerich.
Although determining the correlated color temperature (CCT) of incandescent light sources is fairly simple, as these spectra fit nicely on a blackbody radiator curve, doing the same for fluorescent and LED light sources is much more challenging. Those sources have very different spectral shapes, making it harder to perform an accurate fit using traditional color-filter-based instruments.
