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 camera utilizes an adhesive to hold the lens optically aligned with the imager. After the lens is optically aligned with the imager, the adhesive is initially curable to an initially-cured state in an initial curing process for an initial-cure time period. The initially-cured adhesive is further curable to a further-cured state in a secondary curing process for a further-cure time period that is longer than the initial-cure time period. As further cured, the further-cured adhesive maintains optical alignment of the lens with the imager for use of the vehicular camera in a vehicle.
