Claim:
1. A method of assembling a vehicular camera suitable for vehicular use, said method comprising: providing a lens comprising a plurality of optical elements, wherein said lens is accommodated in a lens barrel; providing a camera front housing having a front portion and a rear portion; providing a printed circuit board, wherein an imager is disposed at said printed circuit board; providing an adhesive in its uncured state; dispensing the uncured adhesive so as to establish a layer of uncured adhesive one of (i) between said lens barrel and said front portion of said camera front housing and (ii) between said printed circuit board and said rear portion of said camera front housing; bringing said lens into focus with said imager and optically center-aligning said lens with said imager; with said lens in focus with said imager and optically center-aligned therewith, initially curing the adhesive to an initially-cured state in an initial radiation curing process that comprises exposure to UV light for a first period of time; wherein the initially-cured adhesive, as cured via the initial radiation curing process, holds said lens in focus with said imager and optically center-aligned therewith; after the initial radiation curing process, further curing the initially-cured adhesive to a further-cured state in a secondary curing process; wherein said further-cured state is achieved within a second period of time; wherein said second period of time is longer than said first period of time; wherein, when further cured via the secondary 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; and wherein the adhesive, in its further-cured state, has a glass transition temperature greater than 90 degrees Celsius and has greater than 50 Shore D hardness.
