Multispectral Area Light Source (600x300mm Emitting Surface) MSL26-3060
The multispectral area light source uses dozens of LED emitters with different peak wavelengths and spectral bandwidths, a precision spectrometer and an independently developed fitting algorithm. Adjusting the amplitudes of its 26 LED channels reproduces target spectra for image color-reproduction testing under different color temperatures, spectra and illuminance levels, with rapid illuminance switching and 60000 brightness levels per channel. One source can fit imported target spectra such as A, H, D50, D65 and D75. Applications include sunlight simulation, multispectral-environment simulation, object color-rendering assessment and whiteness evaluation, with switching between standard illuminants and monochromatic sources. Optional software supports black-body and daylight spectrum matching, preset storage, individual-channel control and cascaded control of multiple sources. It provides a C/C++ API, supports Python calls and runs on Win10/11. Functions include generating standard or externally supplied spectra, independently adjusting 26 channels to produce monochromatic light, saving and importing spectra, creating test sequences, and displaying spectral curves, color temperature, color-rendering index and illuminance. Hardware has 2 types of communication interface, 1 power interface and 1 power switch. Package contents: main unit ×1; power cord ×1 (Chinese-standard length 1.5m, US-standard length 3m); USB Type-A to USB Type-B cable ×1 (3m); RS-485 to USB Type-A cable ×1 (3m); specification sheet ×1; user manual ×1; test report ×1.
