1. A vehicular camera, said vehicular camera comprising:

  • a lens comprising a plurality of optical elements, wherein the lens is accommodated in a lens barrel, and wherein the lens barrel comprises a cylindrical portion;

    a lens holder comprising a cylindrical passageway that accommodates at least a portion of the cylindrical portion of the lens barrel;

    a printed circuit board;

    an imager disposed at the printed circuit board;

    a flexible electrical ribbon cable with one end electrically connecting at the printed circuit board;

    wherein the lens barrel is attached at the lens holder;

    wherein the printed circuit board is attached at the lens holder;

    wherein, with the lens barrel attached at the lens holder and with the printed circuit board attached at the lens holder, optical alignment of the lens relative to the imager is achieved;

    wherein said vehicular camera utilizes an adhesive to hold the lens optically aligned with the imager;

    wherein the adhesive is initially curable in an initial radiation curing process for an initial-cure time period of less than 10 seconds, 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 radiation curing process after the lens is optically aligned with the imager;

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

    wherein, as further cured via the secondary curing process for a further-cure time period that is longer than the initial-cure time period, the further-cured adhesive maintains optical alignment of the lens with the imager for use of said vehicular camera in a vehicle; and

    wherein the adhesive, in its uncured state, comprises a one-part, filled adhesive.
