Abstract: A camera assembly includes a lens barrel assembly comprising at least one optical element arranged about an optical axis. The camera assembly further includes a filter substantially coaxial with the optical axis. The filter presenting a first aperture having a first width for transmission of infrared light and a second aperture having a second width for transmission of visible light, the second width less than the first width. The second aperture may be defined by a center region of the filter that is transparent to visible light and infrared light, and the first aperture may be defined by the center region and a perimeter region substantially surrounding the center region, the perimeter region transparent to infrared light and opaque to visible light.
