METHOD AND SYSTEM FOR EVALUATING LIGHT UNIFORMITY THROUGH AN OPTICAL LENS

摘要

A system for evaluating light uniformity through an optical lens includes an operating platform, an image processing device and a processor. The operating platform includes a mount and a holder. The mount is configured for mounting the image processing device. The holder is configured for holding the optical lens. The image processing device is configured for capturing an image of a light spot corresponding to the optical lens. The processor is electrically coupled to the image processing device. The mount is shifted back and forth along the direction towards and away from the holder for adjusting the size of the light spot of the optical lens. The processor is configured for calculating the light uniformity through the optical lens according to a minimal light spot image from the image processing device.
