Abstract
A reflector can have a conical shape. The shape can tapers from a wide base to an apex. The apex can include an aperture, a mirror, and a set of one or more optical elements. A mirror is location in a cavity and is positioned within an overhang enclosure of the device in a plane approximately parallel to a circular cross section of the conical shape. The mirror can reflect environmental light that is reflected by the reflector into the aperture or reflect light emitting from the aperture onto the reflector. Stray light reflected by the mirror is absorbed by the cavity walls. A set of one or more optical elements can be positioned at least partially within a volumetric region of the reflector. The one or more optical elements focus light passing through the aperture to an image sensor.
