LSB-MSL56-TIR-LR is a professional standard-light solution combining advanced optics and intelligent control. Its 56 selected LEDs and spectral-fitting algorithm accurately simulate international standard illumination from 2000K to 20000K for demanding vision and imaging tests. Applications include imaging, color reproduction, visual object-color evaluation and camera/sensor testing and calibration. Bilateral fill lighting raises chart uniformity above 90%, while CWF, TL84 and U30 fluorescent modes provide flexible, reliable illumination for research, inspection and development. The 56-channel lightbox uses LEDs with 56 different peak wavelengths and an in-house fitting algorithm to reproduce typical ambient spectra. Left/right multispectral sources illuminate a 24-color chart with uniformity above 90%; standard fluorescent alternatives include CWF, TL84 and U30.

Image Colour Retaliation Test 24 colour cards to ensure consistency and accuracy in colour performance by precision validation of colour reduction capabilities of camera modules by preparing a spectrum of multiple colour temperatures and light levels. Low-photo environment tests support separate regulation of brightness levels of LEDs such as white light, which can be used to test critical indicators such as paint clarity, colour reduction, and simulate equipment performance in extreme light settings, in low-light environments below 25lux. Solid-spectural testing: depth verification in multiple scenes. Multiple view viewers can be placed in light-source boxes to enable full coverage of quantitative test needs in the scene, based on dynamic indicators such as white-balanced speed of camera models, and 30 ms of the toleration channel.
Precise spectral reproduction, excellent uniformity, intelligent control and long service life. Broad CCT adjustment: 2,000K-20,000K. Dual-source system: 56 LED channels plus CWF/TL84/U30 fluorescent lamps. Color rendering: CIE Ra ≥97~99 for A/H/D50/D65/D75. LED illuminance >9,000 lux at D65 and >7,500 lux at D50, measured at the center of the inner rear surface, with 60,000 levels. Fluorescent illuminance >1000 lux at the center of the inner bottom surface, with 200 levels. Spectrum: 360–980nm. The 56-channel LEDs reproduce Planckian spectra such as CIE A and CIED daylight spectra over 2,000K-20,000K; built-in CWF, TL84 and U30 lamps reproduce standard fluorescent illumination. Symmetrical left/right lighting improves 24-color-chart uniformity and test stability. Each LED channel supports ≤60,000 illuminance levels; single-channel switching ≤30ms and multichannel switching ≤70ms enable automatic timed spectra. The 7-inch touchscreen contains 100 illuminance presets covering A, H, D50, D65 and D75. Fluorescent lamps provide approximately 200 levels; 2,000K/3,900K color temperatures support ≤60,000 subdivisions. The touchscreen switches illuminance/color temperature for 7 default spectra and recalls 100 user-saved spectra. Computer GUI controls the light source and spectrometer, generates spectra, switches and sequences illumination, and saves unlimited settings. API(C,C++) enables remote control through code.
