Patent ID: 7898663

Claim:
A uniform light generating system for testing an image-sensing device, comprising: a light-generating unit having a substrate and a plurality of light-emitting elements electrically disposed on the substrate; a light-transmitting unit having one side communicated with the light-generating unit for receiving and uniformizing light beams projected from the light-emitting elements; a light-diffusing unit having one side disposed on the other side of the light-transmitting unit for receiving and diffusing the light beams that have passed through the light-transmitting unit; and a lens unit disposed on the other side of the light-diffusing unit for transmitting the light beams that have passed through the light-diffusing unit to the image-sensing device, wherein the lens unit includes a lens set, a focus adjusting element for adjusting the focus of the lens set, and a depth-of-field adjusting element for adjusting the depth-of-field of the lens set.
