A customizable multi-channel LED Calibration Source lighting product to calibrate camera module & sensors in R&D and production line. Simulate various lighting environments to evaluate the performance of your camera or sensors, including tests for auto white balance, color rendering, auto exposure, etc.

The LEDPanel is available in two sizes:

  • 50mm x 50mm
  • 290mm x 224mm

Lead time 3-4 weeks.


● Reproducing high quality blackbody & daylight illuminant – To accurately reproduce a range of sources from tungsten to daylight varying Correlated Color Temperature (CCT) from 2700K to 6500K with CCT accuracy <±50K, and the output SPD is relatively smooth across whole visible range.

● Luminance adjustable and no warm up time – The light is dimmable while keeping the same light quality, and no warm up time

● High uniformity and flicker free light output  – Surface uniformity over 96%, flicker free lighting output

● Excellent stability – Optimized heat management and driver board design guarantees excellent long term stability

● Save up to 80 light sources in the hardware – LEDPanel hardware can save up to 80 light sources, and can be reprogrammed and calibrated via software

● Fast & accurate calibration – Based on the spectrometer and LEDNavigator software, users can measure, reprogram and calibrate the light source. 

● Longer lifetime – Compared to fluorescent technology

● Dynamic lighting – Programmable light sequence and interval

● Software Development Kit in different languages – Allow users to integrate LEDPanel into users’ own software

● LED channel wavelength selection service – Provide LED channel wavelength selection service from UV, VIS to NIR
