1. A vehicular camera suitable for use on a vehicle, said vehicular camera comprising:

  • a lens comprising a plurality of optical elements;

    wherein said lens is disposed at a lens holder;

    a printed circuit board;

    an imager disposed at said printed circuit board;

    wherein one of (i) said printed circuit board is held by a holding element and said lens holder is attached at said holding element by a cured adhesive and (ii) said lens holder is attached at said printed circuit board by a cured adhesive;

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

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

    wherein the initially-cured adhesive, as cured via the initial radiation curing process, holds said lens optically center-aligned and in focus with said imager;

    wherein, after the initial radiation curing process, said lens holder, adhesively attached to one of said printed circuit board and said holding element, is moved to the secondary thermal curing process; and

    wherein, when further cured via the secondary thermal curing process, the further-cured adhesive maintains focus and optical center-alignment of said lens with said imager for use of said camera in a vehicle.
