Zusammenfassung:	A method for assembling an imager assembly for a vehicular camera includes providing a lens barrel that accommodates a lens, providing a lens holder, and providing a PCB with an imager disposed thereat. A cylindrical portion of the lens barrel is disposed in a cylindrical passageway of the lens holder and the PCB is disposed at the lens holder. An adhesive is dispensed to hold the lens optically aligned with the imager. After the lens is optically aligned with the imager, the adhesive is initially cured to an initially-cured state in an initial curing process for an initial-cure time period. The adhesive is further cured to a further-cured state in a secondary curing process for a longer further-cure time period. As further cured, the further-cured adhesive maintains optical alignment of the lens with the imager for use of the imager assembly in a vehicular camera in a vehicle.
