A method and system for mitigating undesirable motion of the optics of a camera are disclosed. The system can include a stage and snubber assembly for defining motion of the camera optics. The stage and snubber assembly can include a stage assembly having a stage to which the optics are attachable, at least one wing formed upon the stage, and a snubber assembly configured to cooperate with the wing(s) so as to limit motion of the stage substantially to the desired direction of travel of the camera optics.

Triaxial snubber assembly

Various lens barrels and lenses are provided which may be used in miniature cameras. In one example, a lens barrel assembly includes a substantially cylindrical lens barrel with a first end including a first aperture and a second end including a second aperture. The first end further includes a first substantially annular portion having a first diameter and a first external surface. The first end also includes a second substantially annular portion having a second diameter and a second external surface. The second diameter is smaller than the first diameter and greater than a diameter of the first aperture. The first external surface of the first substantially annular portion is recessed in relation to the second external surface of the second substantially annular portion. The lens barrel assembly may also include a lens having a portion that protrudes from the second aperture of the second end of the housing.

Lens barrel assembly

Systems and techniques for improved lens barrel tolerance in optical systems. In some embodiments, a lens barrel has a first end section configured to position a first lens with a first diameter and a second section configured to position a second lens with a second larger diameter. The first end section of the lens barrel may include an inner mating section configured to position the first lens and an outer thread section. One of more portions of the inner mating section and associated portions of the outer thread section may be separated by a gap.
