LIS-MSL32-R150

The LIS-MSL32-R150 Multi-spectral Integrating Sphere Light Source combines the high brightness,long lifetime,and high energy efficiency of LED technology with the excellent illumination uniformity of an integrating sphere. It provides precise correlated color temperature adjustment from1800K to 20000K, covers a spectral range of 380nm-980nm, and supports 60000-levelradiant power control. With a USB interface, the light source can be controlled via the supplied software or user-developed applications. Its outstanding uniformity, precise spectral control, and flexible operation make it an ideal solution for wide-FOV imaging lenses and digital camera image-plane luminance and color uniformity measurements.

Features

• Accurate Reproduction of Standard Illuminants

  Equipped with 32 independent LED channels, the system accurately reproduces Planckian radiators from 1800K to 20000K(such as CIE A standard illuminant) and CIE D-series standard daylight spectra.

  
  

• Independent LED Channel Control

  Each LED channel supports 60000-level illuminance adjustment. Single-channel switching takes only 30ms, while multi-channel spectral switching is completed within 70ms. Automated spectral sequencing is supported, with minimum illuminance per channel below1lux.

  
  

• High Color Rendering and Excellent Uniformity

  With a color rendering index Ra>95, true color reproduction is ensured. Luminance uniformity exceeds 90% at the sphere center, providing stable and reliable test conditions.

  
  

• Large Aperture for Wide-FOV Applications

  The 150mm aperture supports up to 220°FOV, suitable for ultra-wide-angle and complex imaging evaluations.

  
  

• Touchscreen and Programmable Control

  A7-inch WVGA touchscreen offers intuitive operation. The system also supports C/C++API and GUI software for automated and integrated test setups.
