Multispectral Light source Box

LSB-MSL26

The LSB-MSL26 is a cutting-edge multispectral light source box featuring tunable LED illumination technology. It offers precise spectral matching by adjusting the irradiance of different LEDs within a wavelength range of 380nm to 780nm, enabling the accurate replication of various light spectra in controlled laboratory environments. For extended capabilities, the LSB-MSL32-IR version reaches wavelengths up to 980nm. Powered by Yanding’s proprietary core algorithm, the LSB-MSL26 utilizes LEDs with distinct peak wavelengths to simulate a wide range of lighting conditions for advanced testing and analysis.
