Abstract
The invention provides, in some aspects, devices for image acquisition that use seals between concentrically disposed portions of an enclosure and an optics assembly in order to protect image acquisition components from the surrounding environment while providing adequate friction for both adjusting and locking focus. Such devices can include an image capture medium that is disposed within an enclosure and an optics assembly that is also disposed within that enclosure. The optics assembly, which includes at least a lens, can have a cylindrical outer diameter along at least a portion of its length that is received within the enclosure along a length that has a corresponding cylindrical inner diameter. A first seal is disposed between, and in contact with, the optics assembly and the enclosure. That seal permits rotation of the optics assembly for purposes of focusing the lens, while preventing contamination from the environment from entering into the enclosure.
