Abstract
A vehicular camera includes a lens accommodated in a lens barrel, a lens holder that accommodates at least part of the lens holder, and a printed circuit board with an imager disposed thereat. The lens barrel is attached at the lens holder by a cured adhesive with the printed circuit board attached at the lens holder, or the printed circuit board is attached at the lens holder by a cured adhesive with the lens barrel attached at 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 curing process that includes UV light exposure for a first period of time. The initially-cured adhesive is further cured to a further-cured state in a secondary curing process that is achieved within a second period of time that is longer than the first period of time.
