LEDPanel Multi-channel LED Calibration Source

THOUSLITE LEDPanel is an innovative light source for camera module & sensor calibration in production line. Based on our proprietary software LEDNavigator and a set of LED channels with different SPD (Spectral Power Distribution), LEDPanel can simulate CCT (Correlated Color Temperature) from 2700K to 6500K with accuracy <±50K. Moreover, the simulated CCT has relatively smooth light output across whole visible range. LEDPanel hardware can save up to 80 light sources which can be measured, reprogrammed, and calibrated using LEDNavigator and spectrometer Excellent optical design guarantees >96% uniformity of illumination surface. SDK (Software Development Kit) in different languages allows users to integrate LEDPanel into their own software
