Abstract
A hood for a digital image-collecting lens includes a base member having a recess defined in a bottom of the base member and to receive an image sensor that has a coupling crystal contained in the image sensor. A through hole is defined in the base member and communicating with the recess and longitudinally and straightly aligns with the coupling crystal. A lens seat is longitudinally and secured in the through hole in the base member and includes a through hole longitudinally and centrally defined in the lens seat. The through hole in the lens seat receives a camera lens of the digital image-collecting lens. At least one annular slot is longitudinally defined between an inner periphery of the through hole in the lens seat and an outer periphery of the lens seat, and longitudinally extending to corresponds to the camera lens.
