1. A vehicular camera including:

  • a lens comprising optical components;

    a lens barrel holding said optical components therein;

    an imager including an image sensor;

    a lens holder;

    wherein the lens barrel is bonded to the lens holder by a cured adhesive;

    wherein the adhesive is initially curable in an initial curing process that comprises exposure to UV light, and wherein the initially-cured adhesive is further curable to a further cured strength in a secondary curing process;

    wherein the adhesive is initially cured via the initial curing process after the lens is brought into focus with the imager and is optically center-aligned therewith;

    wherein the initially-cured adhesive, as cured via the initial curing process, is sufficiently strong to initially hold the lens barrel relative to the lens holder with the lens optically center-aligned with the imager;

    wherein, after the initial curing process, the camera is moved to the secondary curing process;

    wherein, when further cured via the secondary curing process, the further-cured adhesive is sufficiently strong to hold the lens barrel relative to the lens holder for use of the camera in a vehicle; and

    wherein the adhesive comprises an epoxy-amine adhesive.
