Abstract
A method of assembling a camera suitable for vehicular use includes providing a lens accommodated in a lens barrel, a camera front housing, and a printed circuit board with an imager disposed thereat. An adhesive is dispensed to establish a layer of uncured adhesive one of (i) between the lens barrel and a front portion of the camera front housing and (ii) between the printed circuit board and a rear portion of the camera front housing. With the lens in focus with the imager and optically center-aligned therewith, the adhesive is initially cured to an initially-cured state in an initial radiation curing process that includes exposure to UV light for a first period of time. The initially-cured adhesive is further cured to a further-cured state in a secondary curing process. The further-cured state is achieved within a second period of time that is longer than the first period of time.
