Abstract: An optical proximity sensor includes a housing, an optical emitter, and an optical detector. A first light guide disposed in a first chimney of the housing is configured to direct light from the optical emitter through the first chimney towards a target location. A second light guide disposed in a second chimney of the housing is configured to direct a returned portion of the light emitted from the optical emitter through the second chimney towards the optical detector.
