Abstract
An ambient light sensor of an electronic device is calibrated using a calibration device and method which combines multiple sources of light having different wavelengths into a single calibration beam of light. This calibration beam of light provides a consistent and reproducible methodology for testing and calibrating the ambient light sensor.
