Abstract
A novel digital camera module includes an image capture device, a lens unit including a body, a housing including an opening for receiving the lens unit and positioning the lens unit with respect to the image capture device, and a contaminant trap formed by an isolated annular space between the lens unit and the opening of the housing. In a particular embodiment, the opening of the housing includes surfaces having at least two different perimeters, the smaller of which slidably engages the outer surface of the lens unit. The contaminant trap collects and contains any contaminants before they reach vulnerable components such as the image capture device and/or other optical components within the camera module.
