26-Channel Multispectral Light Box (Visible)

LSB-MSL26 Multispectral Light Booth is a high-precision visible-light illumination system designed for camera imaging, color analysis, and machine vision testing. Equipped with 26 independently controlled LED spectral channels covering the 380–780 nm visible spectrum, and integrated with TL84 and CWF fluorescent lamps, it accurately reproduces a wide range of standard illuminants as well as user-defined spectral distributions. The system supports an external spectrometer and utilizes advanced spectral fitting algorithms to faithfully simulate CIE A, H, D50, D65, and D75 standard illuminants. Each LED channel provides 60,000 levels of independent intensity control, enabling precise spectral reproduction, color temperature adjustment, and illuminance control. It provides a stable, consistent, and repeatable lighting environment for camera color reproduction evaluation, white balance verification, ISP tuning, low-light imaging tests, and machine vision inspection.
