Abstract: An electronic device can include a housing that includes an optically transparent component. First and second light emitters can be positioned in the internal volume defined by the housing. A light detector can be positioned in the internal volume and can be optically isolated from the first and second light emitters within the internal volume. An opaque material can be disposed on the optically transparent component and can be positioned to inhibit light emitted from the second light emitter from reaching the light detector and to allow light emitted from the first light emitter to reach the light detector.
