Abstract
A method of assembling a camera suitable for vehicular use includes providing a lens accommodated in a lens barrel, a lens holder, and a printed circuit board with an imager disposed thereat. An adhesive is dispensed to establish a layer of uncured adhesive (i) between the lens barrel and lens holder or (ii) between the printed circuit board and the lens holder. 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.
