    Abstract: An imaging system (60) comprises a housing (200) with reference surfaces (274,276), a lens (570) in contact with the reference surfaces (274,276), a member (600) retained to the housing in contact with the lens, and a spring (720) located between and in contact with a portion (282,332,342) of the housing and the lens. In a first operating condition, the member (600) is retained to the housing at a first location (350,360,370,380) and the lens is translatable with respect to the housing (200) and in a second operating condition, the member (600) is retained to the housing at a second location (420,424) and the lens is not translatable with respect to the housing.

    Abstract: In an imaging system (60) of the type having a photosensor package (510) and at least one optical component (570), e.g., a lens, mounted within an optical assembly housing (200), the photosensor package (510) is mounted to a substrate (540), such as a printed circuit board, which has a shorter length than the photosensor package (510). This shorter length causes the ends of the photosensor package (510) to extend beyond the substrate (540) and, thus, be exposed. The exposed ends (524, 526) of the photosensor package (510), in turn, allow the photosensor package (510) to be directly referenced to reference surfaces (442, 446, 450, 452) formed on the optical assembly housing (200).

    Abstract: In a lens focusing and holding arrangement for an imaging system (60) including a photosensor array (510), the lens (570) is in contact with a reference surface or surfaces (274, 276) formed within the imaging system housing (200) and is translatable along the surface (274, 276) in directions toward and away from the photosensor array (510) in order to adjust the focus of the imaging system (60). A lens retention clip (600) is provided to secure the lens (570) within the imaging system housing (200) and to cause translational movement of the lens (570) along the imaging system reference surface (274, 276). When focusing the imaging system (60), the lens retention clip (600) is in a first operating condition in which the lens retention clip (600) applies a relatively small force tending to hold the lens (570) in contact with the housing reference surface (274, 276). After the desired focus has been set, the lens retention clip (600) is placed in a second operating condition in which the lens retention clip (600) applies a relatively high force tending to hold the lens (570) in contact with the housing reference surface (274, 276), thus locking the lens (570) in place.
