LSB-MSL32-IR Spectrally Tunable Multispectral Light Box is a high-performance multispectral illumination system integrating both visible and near-infrared (NIR) illumination capabilities. Equipped with 32 independently controllable LED spectral channels, the system covers a broad wavelength range from 380–980 nm and integrates TL84 and CWF fluorescent light sources along with a built-in high-precision spectroradiometer, enabling accurate simulation of standard illuminants, customized spectral profiles, and near-infrared lighting environments.
By combining advanced automatic spectral matching and auto-calibration technologies, the system can precisely reproduce standard illuminants including CIE A, Horizon, D50, D65, and D75. Each LED channel supports 60,000-level independent intensity adjustment, enabling high-precision spectral generation, color temperature control, and illumination adjustment.
The LSB-MSL32-IR is widely used for color reproduction evaluation, white balance testing, and image quality assessment of advanced vision systems, including RGB cameras, RGB-IR cameras, near-infrared imaging systems, ToF sensors, LiDAR, ADAS cameras, and smart cockpit vision systems. It provides a stable, accurate, and repeatable controlled lighting environment for next-generation imaging system development and validation.
