Abstract
A vehicular camera includes a lens, a printed circuit board and an imager. The lens has a plurality of optical element and is disposed at a lens holder. The imager is disposed at the printed circuit board. The adhesive is initially curable in an initial radiation curing process that comprises exposure to UV light, and initially-cured adhesive is further curable to a further cured strength in a secondary thermal curing process. The adhesive is initially cured via the initial radiation curing process after the lens is brought into focus with the imager and is optically center-aligned therewith. The initially-cured adhesive, as cured via the initial radiation curing process, holds the lens optically center-aligned and in focus with the imager. After the initial radiation curing process, the lens holder, adhesively attached to one of the printed circuit board and the holding element, is moved to the secondary thermal curing process.
