1. A device comprising:
a quadric reflector having a conical shape, which tapers from a wide base to an apex, said apex comprising an aperture;
a mirror positioned within an overhang enclosure of the device in a plane approximately parallel to a circular cross section of the conical shape, said mirror reflecting environmental light that is reflected by the quadric reflector into the aperture or reflecting light emitting from the aperture onto the quadric reflector;
the overhang enclosure having a conical shape, which tapers from a wide base at a topmost portion to a narrower center, wherein the mirror is positioned at the narrower center or positioned within a concavity of the narrower center, wherein circular cross sections of the overhang's conical shape from the topmost portion to the narrower center portion have a diminishing circular cross section, wherein a taper of the overhang is inverse to a taper of the quadric reflector, wherein an outer tapering surface of the overhang enclosure between at least the topmost portion and the narrower center portion is formed from or coated with a light absorbing material, wherein the conical shape of the overhang enclosure permits environmental light to reflect off the quadric reflector without operational blockage while the substantially conical shape absorbs secondary reflections to prevent them from entering the aperture;
a set of one or more optical elements positioned at least partially within a volumetric region of the quadric reflector, said one or more optical elements focusing light passing through the aperture; and
a transparent outer casing with a circular cross section, wherein a topmost portion of the overhang is secured to a topmost portion of the transparent outer casing, wherein a bottom most portion of the transparent outer casing is secured to a structure that supports the quadric reflector, wherein an interior volume of the transparent outer casing includes the quadric reflector, the mirror, and the overhang enclosure.
