Abstract: A charge coupled device (CCD) with multi-focus lengths is provided. The arrays of optical sensors with a plurality of transparent plates in parallel disposed thereon are disposed on a substrate. By way of either of changing the thicknesses of the transparent plates and changing the position levels of the arrays of the optical sensors, each of the arrays of the optical sensors obtains a different focal length. And thus, the depth of focus of the present charge coupled device is improved.
