The YD-MSL Multispectral Light Source Control Software is a professional platform tailored for multispectral standard light boxes. It enables independent control of each light channel, supports spectrometer and meter feedback, and allows generation and fitting of target spectra. Users can save custom light source configurations, automate illumination sequences, and monitor photometric and colorimetric parameters such as illuminance, correlated color temperature (CCT), color rendering index (CRI), and spectral distribution in real time.
