The MSL-XL-TIR series multi-spectral vertical illumination source is a professional auxiliary lighting system developed based on tunable LED multi-spectral synthesis technology. Through a Multi-peak LED array + Spectral fitting algorithm architecture, it enables precise reproduction of standard illumination sources and flexible simulation of multiple lighting conditions. It provides high-fidelity, repeatable, and controllable spectral output to support objectives such as imaging evaluation, color reproduction verification, and sensor calibration, covering full-scene testing needs from complex composite spectral light sources to monochromatic illumination environments.
Key Features
Accurate Reproduction of Standard Illumination Spectra
32 / 56 LED channels allow precise reproduction of Planckian radiators (e.g., CIE A) and CIE D-series daylight spectra across 1,800K–20,000K.Flexible Configuration for Multi-Scenario Lighting
Supports stand-alone use, multi-unit combined illumination, and large-scale light-room construction, enabling applications ranging from small samples to large chart environments and batch imaging verification.Independent Channel Control with High-Speed Spectral Switching
LED channels provide 60,000-level intensity control; single-channel switching ≤30 ms, multi-channel spectral transition ≤70 ms. Supports automated spectral sequence switching and ultra-low-illuminance test conditions.Supports Visible + Near-Infrared Spectral Bands
Covers 360nm–980nm to support both visible imaging evaluation and NIR sensor calibration; optional spectrometer enables precise spectral validation.
