LSB-MSL26 is a high-precision visible-light multispectral lightbox for camera imaging, color analysis and machine-vision testing. Its 26 independent LED channels cover 380–780nm, supplemented by TL84 and CWF fluorescent lamps. An external spectrometer and precise spectral fitting reproduce CIE A, H, D50, D65 and D75 standard illuminants and custom spectra. Each channel has 60000 brightness levels for spectrum, color-temperature and illuminance adjustment, providing stable, consistent, repeatable conditions for camera color reproduction, white balance, ISP tuning, low-light testing and machine vision. The detailed description specifies support for an internal or external spectrometer with the same 26-channel, 380–780nm LED/fluorescent configuration and 60000-level adjustment. Precise fitting reproduces CIE A, H, D50, D65 and D75 and user-defined spectra for the same imaging tests. Standard accessories | main unit, power cord, RS485 cable, specification document, user manual and inspection report.

Applications

Image-white balance testing: Colour-replacement tests to be performed by multiple conventional A, H, D50, D65, D75 photo-sources to ensure consistency and accuracy of colour performance by changing the light environment Low-photo-level testing: to adjust different LED sources to achieve low-phosma tests Image-resilient testing 24-colour-based wall-sort (selected) to ensure the consistency and accuracy of colour performance by preparing multiple chromosomal and photometric spectral spectral spectral spectral resonances, to validate the colour-resistance tropics, to provide for the extreme performance of key LEDs, such as the LED-based LED-based measurements, to be measured separately, to be tested below 25 lux, to be tested for the light-specific radiance radiance, to be measured in a stable, stable, to be measured in a highly extreme environment. Quantification of scenery: Depth validation in multiple scenes. Multiple scenery sets can be placed in light-source boxes to allow for the application of different colour temperatures, light and single-colour light environments by adjusting the spectrum; based on rapid switching performances in LED channel 30 ms, and accurate validation of dynamic indicators such as white-balanced deposition speed of camera models, which fully cover the quantitative test needs in the scene.

Key Features

Standard-illuminant reproduction: with a spectrometer, accurately fits CIE A, H, D50, D65 and D75 over 2000K–20000K. Each of the 26 visible-light LED channels provides 60000 independently controlled brightness levels. The touchscreen recalls A, H, D50, D65 and D75 spectra at 100 brightness levels each without a computer or spectrometer; fluorescent tubes provide 200 levels each. Automatic calibration: an optional Konica Minolta CL500A spectrometer calibrates the 26-channel visible-light box, compensating for aging and environmental variation. LED channels: 26. Spectrum: 380–780nm. Color temperature: 2000K-20000K. Fluorescent lamps: CWF / TL84. Touchscreen and programmed control are supported. Planckian spectra, including CIE A, and CIE D daylight spectra are reproduced over 2000K-20000K. The 26 channels cover 380-780nm for flexible simulation. Radiant power adjusts to target illuminance while preserving spectral quality. An external spectral instrument enables automatic calibration to compensate for aging/environmental changes. Timing mode combines spectra and emission durations into automatic sequences. Measured environmental spectra can be imported and reproduced to standardize or recreate illumination. Software includes source generation, calibration, spectrometer display and channel settings, with API(C/C++) support. GUI or API operation controls individual channels and arbitrary combinations. Integrated TL84 and CWF lamps improve fluorescent-spectrum reproduction.
