Abstract
A fixed-focus camera module includes an image sensor, a lens for focusing an image onto the image sensor, and a positioning structure for maintaining an alignment of the lens and image sensor. The alignment provides a desired image quality of the image focussed onto the image sensor. The positioning structure includes a first unthreaded member coupled to the lens and a second unthreaded member coupled to the image sensor. One of the first and the second members is configured to be inserted into the other of the members to provide an adjustable relative position of the lens and the image sensor.
