Abstract
A containment system for containing an image sensor. The containment system includes a substrate for carrying an image sensor, an optics housing disposed about the image sensor and secured to the substrate, and a foam barrier interposed between the housing and the image sensor or between the optics housing and the substrate. The foam barrier of the containment system prevents the intrusion of particulate and stray light rays into the containment interior. Further, the foam barrier traps particulate so as to inhibit the free circulation of particulate in the region surrounding the containment system. Because it allows for a circulation of air into and out of the containment system, the foam barrier encourages the evaporation of condensate which may form on the contained image sensor and/or optical lens components.
