Abstract: Techniques for facilitating wide field of view (FOV) imaging systems and methods are provided. In one example, an imaging device includes a lens barrel. The lens barrel includes a first body portion including a first lens element at least partially disposed therein, a second body portion including a second lens element and a third lens element at least partially disposed therein, and a snap-fit mechanism. The first, second, and third lens elements include a lens system configured to pass electromagnetic radiation from a scene to an image capture component. The snap-fit mechanism includes a plurality of finger members extended from the first body portion and a plurality of complementary notches in the second body portion. The finger members are configured to engage with the notches to releasably secure the first body portion to the second body portion. Related methods and systems are also provided.
